Some people are a little too much, yes. But how can Arkane have most of the responsibility when it is Microsoft who control all decisions? When it was time to cancel the PS5 version, they were there. When it was time to heavily market the game, they were there. When the game was close to the first date and a delay was needed, they were there. And now they choose to publish it in this state. If arkane lied to Microsoft, then yes it is their fault. But even then, from a outsider perspective it is Microsoft fault, as they should have looked hard at the game before it was out. All games need a certification. And Microsoft gave it. No suprises here.
I am not saying that arkane has no blame here. They do. But they lost all control of themselves a long time ago. And Microsoft( and Phil) has explained pretty well what happened. But they could have delayed or cancelled the game. By not doing it they have to take most of the blame. The 70$ that they get when someone buy the game go to Microsoft. So they have to take the good with the bad.
As for bend, or any Sony first party game, I am not so sure. If the game is out with no bugs and good graphics you can't complain that much. Rest gameplay, story... and that is the studio that work on that. But if a game is out full of bugs then I can see Sony taking some blame, like for the TLOU PC port. I hope that you would agree with the difference.
