I'm from that generation, more or less, and still think it's pretty rude to download stuff that you didn't pay for. I'm against supporting broken business models that don't let you store the media in the format that's most useful to you (eg on a media center) but that still doesn't mean that you get to download stuff illegally.
The smart thing to do would be to concentrate less on prevention - people are always going to copy stuff no matter what - and focus more on detection. Find the people who are downloading your stuff and get them, rather than making stuff harder for the rest of us.

They must also then actually get around to *writing their own* music. And while you're doing that, you have to earn money to meet the million other obligations of daily existence - food, clothing, shelter, utilities, transportation... all of this costs money and/or time.
To suggest that the process of making music is more or less zero-cost - "cost of creation is negligible" is either willfuly ignorant or absurdly naive. It requires a lot more than patience.

Production AND distribution are a very small portion of "content creation," whether it be a P2P distribution scheme, or shipping by trucks to hundreds of stores around the country.

Uhh...I thought the big advantage of electronic distribution was that it's far cheaper than creating physical articles. I can get a server with 100mbit bandwidth + 10TB monthly transfer for $350/mo -- that will let me distribute 300K albums (at 30MB each). Or, one tenth of a cent each.

I don't think you can press a CD for that little, even if you're buying 10 million of them at a time. I'd bet that the setup fee for a big CD run costs more than hosting the website for 6 months or a year.

The HDCP 'protection' was a delusional attempt by the content providers to get a step ahead of pirate-copy-makers. They fantasized that their current media protection was 'perfect', so figured pirates would start copying from the video connection.
Of course, their protection wasn't perfect, so copier have continued to just strip the DRM off the provided media instead of rigging weird setups to copy from a monitor cable.
Which copiers could do anyway, as HDCP decoders have existed forever. This crack was the master key...before that, you had to buy a 'licensed' piece of hardware that could strip HDCP, which is fairly easy to get, although you have to order from overseas. With this crack, now, you can simply record the encrypted signal and decode it, I guess. (Maybe not, though.)
But no copier did that, or will start doing that. They'll just remove the BlueRay or cable encryption instead, like they've been doing.
In short, HDCP was 'second-level' DRM, which required, as a base assumption, that no one would be able to decode DRM before it get outputted, so HDCP was an attempt to protect the output. As people can decode the DRM before output, it's, um, utterly pointless to crack.
Even if copiers were copying from there, none of that has anything to do with 99.9999% of pirates, who download copied movies,and thus could give a flying fuck where the copy came from. Any HDCP connections will display a pirated video as well anything else.

A friend of mine couldn't play a couple of Blu Ray discs he'd bought because of various compatibilty issues to do with updated keys or whatever. It convinced me that Blu Ray just wasn't ready for the living room. Why would I want to give these fools my money when it results in a crapshoot? No Blu Ray player for me, no discs either. I decided to spend my money on something that's not so flaky.

Nobody had to give it out. The encryption is weak, and it has been known for a long time that it would be possible to derive the master key given data from a sufficient number of devices. I'm surprised it took this long for someone to actually do it.
Re:Who revealed it (Score:4, Interesting)
Why did they bother to use weak encryption? Is it not trivial to make longer formulas etc. ?
There are two possible answers.
1. They didn't get smart enough people to design the system (see DVD CSS).
2. The complexity of the key system was limited so as to allow small/cheap/embedded devices to implement it with limited processing power and speed.
I'd say option 2 is more likely, but wouldn't be surprised with option 1.

Actually the master key doesn't exist on all devices. The master key is theoretically kept private and managed by the consortium that oversees HDCP. When a new vendor comes along then the HDCP consortium generates a sub-key from the master key and assigns it to that vendor. The vendor then uses that sub-key to create "sub-sub-keys" for each device they manufacture.
If a device key is compromised then the vendor can revoke it and issue a new sub-sub-key for the device. The HDCP consortium could also revoke the sub-key for the vendor, thereby invalidating all the vendor devices, if necessary.
The problem with the HDCP encryption is that if you have enough of those device keys (50 or so according to reports) then with a bit of grunt work you can reverse-engineer the HDCP consortium master key. That's apparently what happened in this case.

Because, as in all things, most people are honest.
If I want a movie, I buy it. That might mean buying it second-hand, or buying it from a friend, but I don't do the shady deals in pubs with strangers. Most people are like me, and most people actually pay for stuff. VCR's and DVD-R's are, of course, used for piracy - because they are recording devices. But if you didn't have those, people have camcorders, or webcams, or any one of a million and one recording devices.
The recording device, or the technology built into any recorded media, does not stop anything, at all, ever, except genuine, honest customers doing something quite reasonable. Anyone who wants an illegal copy can get one in any one of a million different ways. Hell, the early DVD rippers basically screenshotted the screen of a DVD player so many times a second and recorded the audio. It's not hard at all, because of the "analog hole". But the only people who bother to go to that amount of effort are established pirates and those who genuinely believe they are doing something quite reasonable and should be allowed to do it.
Despite popular opinion, that's NOT the majority of people.

It gets worse actually, with HDCP you cannot use signal splitters or other devices like scalers or converters that are frequently used in professional projection and scientific setups. If you do, you will get snow (not immediately, just sometime down the road when somebody has loaded HDCP protected content) on the whole display (not just the content) making those things useless. If you use a splitter for example, you have to go out of your way and buy another device ($80) to sit on the primary channel to make sure it can't negotiate the HDCP encryption. But HD content will still play even if you don't have an HDCP-compatible setup (as there is no content I know off yet that forcefully locks people out of their Chinese/Wal-Mart TV/Blu-Ray el-cheapo knockoff setup), it's just that if you do have an HDCP-compatible setup (and you paid good money for eg. Dual-DVI KVM, splitter, displays and projectors with high-res 120Hz signals for scientific research), it will malfunction.
HDCP really has no legit reason to exist (Score:5, Insightful)
As you say, there are two separate issues, the issue of respecting copyright and the issue of doing what you want with your devices. Well HDCP does nothing to stop copyright infringement. The pirates just nab a copy earlier in the chain, just rip the disc. Sometimes they do it later in the chain, just record a movie in a theater. Either way the fact that they can't nab a signal from the wire doesn't matter at all, they don't even try.
What this does do is prevent legit uses. I really want to build a HD DVR for my living room. I don't want the one the cable company sells. Not only do you pay a monthly charge, but I don't care for its features or its tiny drive. I want to build my own. The capture card I want is already on the market, the Blackmagic Intensity. Expensive, but worth it. ...
Except HDCP stops all that from working.
So I could go and just download the content online, any and every thing I could want is out there, free for the taking. I cannot legitimately just record it off my expensive ($80/month currently) cable TV connection.
I'm very fed up with copy protection these days because this is what is happening. It isn't protecting anything, it is hurting normal users. It is so overbearing that it interferes with normal usage, and still it does nothing to stop infringement.
Another thing, along those lines, is I can't play Blu-ray movies on my PC. I have a BD-RW drive, 1920x1200 monitor and HDMI soundcard out to a massive home theater system. Seems like the tech is there. However because of the way my system works, the display output is mirrored, one copy via DVI to the screen, the other via HDMI to the soundcard, since it need a video signal to get clock from to send its sound. All devices HDCP enabled, but Blu-ray disallows playback in the event of a mirrored screen.
They've done a great job of protecting me from myself, but nothing to stop me from downloading a program and ripping and uploading their movies, if I so chose.

* The generated manufacturers' keys are set up in a way that device A and B can communicate secretly without knowing each others' keys.

Like all encryption systems - if you learn enough about the keys, you can crack them and recover the original keys. In this case, just 40 devices with HDCP and a lot of mathematics is virtually guaranteed to recover the master key.
Don't use encryption to secure a digital product. It *will* fail because, at some point, you have to give people a key to access that product - thus they have access to the decrypted stream and to a number which is reliant on the private key. Encryption does NOT take account of protecting against an authorised user with a valid decryption key, or numbers of those users working in a concerted effort to crack your encryption. It's a misuse of the technology and any company that claims the opposite (e.g. all DRM companies) are lying to you.

Which is exactly why some people decide "fuck it" and go and break people's copy protection schemes. 1% of your customers is a big chunk of your income, especially in a economic slump. And that 1% are likely to be the most tech-savvy, probably quite large consumers of such content and, by strange coincidence, quite capable of destroying your petty copy protection and letting everyone in the world have it, safe in the knowledge that that life in a non-DMCA

Copy protection using encryption is inherently insecure, because you have to give genuine customers some way of viewing material, thus some way to break the encryption. The second you do that, you are going against the established design criteria of modern encryption. No encryption specifically guards against multiple genuine recipients having multiple, genuine, valid decryption keys for ever and ever, and preventing *ANYONE* (even the genuine recipients) from ever decrypting that content.
