My take is that I notice that people who want to push bigotry, sexism and other identity-based strife tend to want to infect any circle where people of all identities gather. The folks pushing such agendas in sci-fi fandom, sports fandoms, games etc, -- the subject itself is irrelevant to them.
It merely gives them access to the social media connection matrix they can use to spread their vileness. Everyone who follows said subject matter now gets fed hateslop by the algorithm.
They want to create strife and division everywhere. They don't care about D&D. They'll burn it to the ground. It's merely a key to an algorithm for them.
But D&D, being something run at individual tables, is surprisingly resilient against any permanent detrimental change. If some billionaire decided to buy the company tomorrow, it wouldn't affect my game at all. Nobody decides what hits my table but me.
