The most damaging thing for Roiland wasn’t the DV allegations, it was all of the profiles and statements by his co-workers basically saying his contributions and participation in “his” products was essentially zilch. That already seemed like a pretty open secret at that point anyway, to the extent most people used him essentially for marketing purposes only. This just sped up everyone knowing it.
THAT may actually be harder to recover from, because it has nothing to do with canceling him. It’s his issue in the workplace.
