There was actually a class-action lawsuit about this, but Sony played a lot of games to keep the rationale for locking out OtherOS out of the discovery process.

There was actually a class-action lawsuit about this, but Sony played a lot of games to keep the rationale for locking out OtherOS out of the discovery process. It wound up being just another one of those kinds of settlements - i.e. a large-sounding number being awarded to so many plaintiffs in the class that its basically pennies per person. My guess is that they don't want to say the quiet part out loud: i.e. they took away OtherOS because they weren't getting the tariff exemptions they wanted and they don't actually want people using these devices for non-royalty-bearing activities (e.g. piracy and homebrew).
