Sony can’t just decide solely at their digression which games require PSN integration and which ones don’t. That is a joint decision between the developer of the game and Sony.
Sony can’t just walk into Coffe Stains office for example and demand all players of Goat Simulator now require a PSN account; Coffee Stain would have to decide to agree to that.
Arrowhead didn’t have to agree to it, but they did. Now they have to deal with the consequences of that decision.
No they didn’t. They could have negotiated different terms, gone to a different publisher, became their own publisher.
This is the route they decided to take. I’m sure there were plenty of other factors tied to that decision, but it was still entirely their decision to make.
I don’t know why you continually refuse to acknowledge the difference between making a decision and agreeing to allow something.
That would be because agreeing to allow something, is a decision.
A partnership with Sony and the terms that come with that were not forced upon Arrowhead, they decided to agree to it. Plain and simple.
