That's BS. Linux/OtherOS on the PS3 only existed so that Sony could evade European tariffs on pure gaming consoles that were markedly higher than on general-purpose computers. Once the tariffs went, so went OtherOS support.

In any case OtherOS didn't have access to the full system resources and, on top of that, Sony actually lost money on PS3s because it was priced as a loss-leader, with game purchases being supposed to earn the actual money.
