I can only assume that in buying a CD with copy protection on it, that legally holds as an agreement to accept the software. However, I have never bought such a CD so don't know how it is sticker, if at all. I'm dubious.
From what I've read in recent months, the clued-up people have return their CDs and demanded a refund. Hopefully, the record industry will get the hint. Especially when I read about Mike Oldfield's last record was copyright protected worldwide (except Canada) in an effort to stop piracy, and the album appear on the internet within hours of being released.
I don't do file sharing anymore, mainly due to the security issues. However, in the 70s/80s there was a big push with 'Piracy is killing the music business', when blank cassette buying reached an all time high. Unfortunately what many didn't realise is that much of the tapes were being bought to record live gigs, and then swapped between fans. Admittedly there were people who recorded albums for their mates. I used to record them so I could listen to them in the car. But it didn't kill the music business.
Piracy as it exists today is not going to kill the music business. However, the attempts by the record industry to disuade people buying CDs ever again and move to download from the internet is likely to serverely harm the record companies. Bands and artists who go out on the road or make and sell their music on a small budget, will likely survive for many years to come.
