They should be given kudos for even trying, not blame for failing at what appears to be an impossible task. Sony thought they could offer Linux-on-PS3 and still keep the PS3 secure. For a while it seemed to work, but eventually it was demonstrated that Linux-on-PS3 broke the security model of the PS3. Sony really had no choice, because it's a gaming console first and foremost and they had to protect that. Yeah it sucks for everyone who was interested in using it as a Linux machine, but if you can't recognize that Sony had an obligation to protect the gaming console over the Linux support, I don't really know what to say to you.

However you view it, the damage is done.
