The lawsuit gives several examples to establish that Activision Blizzard discriminated against him, starting with statements Bobby Kotick allegedly made at a leadership conference that the "problem" with Activision Blizzard is that "there are too many old white guys." (The suit doesn't say exactly when the conference was.)

Shit, I'm discriminatory against old white guys too; I don't trust that I'm not going to hear some old sundown town shit out of them anymore
