Just because the game failed doesn't mean the whole studio needs to be scrapped... Artists and programmers could still get their chance to shine, without the top level decision makers steering the game towards dated formulas like hero shooters
I mean I also doubt the director was behind all the bad decisions that led to this. Cause this game started development back when Overwatch 1 came out. It wasn't an old formula then, it just took too long to come out. That could be the directors fault but from what I've heard it was more decisions from corporate to chase new fads like live service and more that ended up delaying it so long and causing it to become dated.
Sony hasn't hesitated to shut down their GOOD studios before (like Zipper Int). They've even shut down studios right as they released games before (PS All Stars Battle Royale).
Why's it different now? Sony is a garbage company.
