@Peter I don't see the point of the analogy.
A product was sold, and bought by consumers, to have features:
1 Play BluRay discs.
2 Play legally purchased Games standalone (released prior to 1st of April 2010)
3 Play legally purchased Games standalone (released post 1st of April 2010)
4 Play Network Games.
5 Install OtherOS.
Sony after sale decided that customers can have a subset of these features (1,2,5) and not others (3,4). Or you could update the firmware and have access to less features than the date of purchase (1,2,3,4). A modern day spin on the classic bait and switch.
Some very smart people were unhappy with this and are currently trying to (re)add features to hardware they own.
5b Install whatever OS on the hardware they own e.g. Linux, FreeBSD, NetBSD, ...
6 The ability to legally run whatever software they like on the hardware they own, software refered to as homebrew . e.g. XBMC, a proper web broswer, email client.
Now they are seeking what they bought (1,2,?3?,5b,6).
The people currently involved have no interest in software piracy, it is illegal. But as a consequence of their work it will happen.
When the first link in a security chain is broken, it is going to be near impossible for Sony to repair the chain. One way to make life harder for piracy would be to release a new firmware, with new sub-keys every few days/weeks. But the hardware failure rates for the PS3's flash memory would sky rocket.
