It was clearly advertised on the steam page, but also on launch you had a full screen banner that said you MUST sign in with a PSN account to play this game. It's just that until now you could click cancel and the game would still launch.

So no, nothing was "added".

Sony was/is selling steam codes on their own store with a QA that clearly explains that PSN accounts are not required for PS games on PC
