Early versions of the PlayStation 3 system software also provided a feature called OtherOS that was available on the PS3 systems prior to the slimmer models launched in September 2009. This feature enabled users to install an operating system such as Linux, but due to security concerns, Sony later removed this functionality through the 3.21 system software update. According to Sony Computer Entertainment (SCE), disabling this feature 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. Sony was successfully sued in a class action over the removal of this feature. The settlement was approved in September 2016. Sony agreed to pay up to $55 to as many as 10 million PS3 owners but denied wrongdoing.
