I don't see that as the real problem, the only problem I see is PC influencing the types of games PlayStation studios are going to be making, but maybe all these GaaS were already going to happen regardless of PC.
Something else that Sony used to have that I think it would make sense for them again are studios dedicated to PC gaming, that way it won't get as much in the way of what is already working for their AAA console-style games. I don't want to see Insomniac working on a MOBA or something weird like that.
