An hour after this announcement was made, a tiny update was pushed via GamGuard to steam players and now there's a .DLL file that's being flagged by antivirus as a malware. My AV detects and cleans the file, making the game completely broken. There a Steam discussion about this issue and, surprise surprise, the file in question is used by GameGuard.
Good for you? The post isn't about people like us playing on PlayStation, it's about people like my buddies I play with that thought they were good to go with their steam accounts and are now being railroaded a few months later by having to give their data to PSN, who is notorious for not managing said data well.
"It's in the ToCs", you might say, which is only highlighting a broader issue where you basically have to wade through pages of legal bullshit to just play a game you bought and not get fucked by the EULA.
