It Sony's fault for putting a lock on their hardware to protect illegally copied software from running, and it was this action that FORCED the hackers to break that lock, plus its Sony's fault for making the PS3 too cheap and for not selling software at the price buyers want to pay, and its Sony's fault that people want their software for free?
To me it is simple. It should be legal to hack something one has bought to do whatever one wants to do with it; be it software or hardware. EULAs should be overruled by law it they try to prevent that. Business models that are not compatible with this have to adapt.
It should and is illegal to use something one has not bought; be it stolen hardware or copied software. People not abiding by this may get punished. Piracy needs to be prevented, and services like piratebay IMO may be shut down or blocked until these sites finds a way to remove most of the links to illegal stuff on their site.
