TL;DR: Employees say his actions led to a lot of direction changing that forced management to scramble, and the lower workers had to bear the brunt of this. They also complained that OW2 needed more work or would be review bombed on Steam and his leadership refused. Shareholders are still happy to fellate him though because he made them a lot of money.
I'm genuinely worried for Bungie and Destiny 2. It's like "We get it, we let our players down. We are going to fix it by firing the current CEO and hiring Bobby Kotick..."
Bobby going to Bungie is only an uncomfirmed rumor.
However, I will never forgive Bungie.
They did Marty and Joe dirty, Marty by trying to rescind his company shares and Joe for the way Jason Jones treated him in Destiny 1s developement
They absolutely ruined Destiny 1 and 2, though 2 far more than 1
They deleted content that I paid for without my permission, removing my ability to choose to access it (this is when I stopped playing Destiny altogether)
They're tarnishing Marathon's good name by making it a PvEvP extraction looter shooter
"We want you to throw money at the screen" famous quote (they really thought it was a good idea to say that)
If Bobby does become CEO there, I would not be surprised. But I actually dont think its possible for Bungie to get any lower.
I've seen that they understand players are leaving in droves, but I've seen no indication that they know why. Every single thing they've said an done since the last DLC has been exactly the opposite of what makes the game fun for me. I went from spending way, way, way too much time each week to spending virtually none in a single season... And I haven't even checked on the game since the second week of this season. It's really sad.
