Yeah I can almost guarantee that the original plan was always for him to leave. He was going to be the scapegoat with a golden parachute, allowing the company to keep the unpopular changes while disbursing the bad publicity. It’s exactly what he did with EA too.
Basically reddit’s Ellen Pao plan. Bring in someone unpopular to make the unpopular changes, then let them go with a massive payout while keeping the unpopular changes.
But then Unity realized that the companies weren’t going to forget about the unpopular changes and it wasn’t going to blow over. Companies started bailing left and right and switching to other engines. At that point Unity realized that the smoke was actually a full blown fire, and started doing whatever they could to try and regain some trust. But by that point it was too late, because companies had already seen the potential for abuse. And as the saying goes, when someone tells you who you are, believe them. So now companies are unwilling to go back to Unity, and Unity is grasping at straws.
