PS3 Firmware 3.21 removes Linux support
Sony is releasing the 3.21 PS3 firmware on April 1 and it's no April fools joke: PS3 owners will lose support for Linux and the 'OtherOS' install. The PS3 3.21 firmware does nothing else-no added features, game support-it just removes functionality. Sony is citing 'security concerns' but we all know that is a codeword for piracy.SCEA's Patrick Seybold explains that the removal of said functionality is necessary "due to security concerns ... [and] will help ensure that PS3 owners will continue to have access to the broad range of gaming and entertainment content from SCE and its content partners on a more secure system." I call bullshit on this one, Sony is out to squash the OtherOS exploit before it can be used for piracy.
If you wish to keep your Yellow Dog, or any other Linux install going on your older PS3 you will have to opt out of the 3.21 firmware update. The downside is that you lose the ability to play back DRM protected video stored on a media server OR play any future PS3 titles that require the 3.21 (or higher) firmware. PS3 owners who opt out of the 3.21 firmware update also can't sign into the PlayStation Network, which means no more online play or chat.
This reminds me of the constant battle that Sony has been fighting with home brew/piracy on the PSP. It seems that they update the firmware every other day to try and they still are unable to prevent people from using the PSP how they want. It's sad to see Sony start down this path with the PS3 and removing a feature because it MAY lead to home brew or piracy. Why not let patch the exploit in a way that still allows the OtherOS?
