In what world is that a mobster deal? The game initially released saying that PSN accounts were required, this is in every store front description. The devs clarified that was not enforced due to technical issues at release time.

Sony funded the game in the first place too. They didn't take advantage of a moment of weakness. This is all contract stuff agreed upon long before release.

It absolutely sucks ass, but this is an incredibly basic business deal. Sony stepped in to provide server support because it's Sony's game, and Sony makes money off it. Now that the game is more stable, they likely went back to Arrowhead and said "Hey, it's time you sorted out the contracted requirement for PSN accounts. You agreed to this." and here we are.

Maybe Sony told Arrowhead that PSN accounts could be made by everyone. Maybe Arrowhead thought they could push back on the requirement after the game came out without them required. We likely will never know what went on behind closed doors.

But this isn't shady, just absolutely monumentally fucking shitty.

Unfortunately, as long as refunds are handled reasonably well like they were with Cyberpunk 2077's PS4 release, gamers won't really have a leg to stand on. It'll just be complaining that they can't play something they wanted to play, after getting a number of hours in it for effectively free.
