The "Grey Tribe" techbros and techbro stans of the "LessWrong" cult insisted they weren't political while announcing over and over again that the robot god requires billionaires to get richer and faster. 
used to have such an unassailable PR fortress going that even some leftist communities had struggle sessions about him. One of the most naive ones ever even said that he might bring "reason" to the then-upcoming Trump regime. 
I remember 
being declared "nonpolitical" by his cultists.
Joe Rogan of course had the "he sometimes has a lib on his show so he's strictly nonpolitical even while mostly signal boosting fascists" thing going for a while but I think no one really believes it anymore, not even his devotees.
Most recently, "MrBeast" started to visibly ride the chud slide, even if he was more incognito for a while because of the garish facade of le epic charity grifting.
Anyone actually remain in the plausible pretenses of nonpoliticalness that you know of?
Thinking of some of the counte- strike streamers I follow. They attempt to be non political but fail. WarOwl is a conservative but knows that being a conservative cuts his audience in half, so he stays closeted but leaks things like his Ronald Reagan calendar and sponsored videos he did with the marine corps. Fl0m does a better job avoiding politics and I think he himself is likely a moderate, but he plays on a team with a frothing chud (Cooper) and his brother (freakazoid), so he is in that sphere of influence.
It ultimately leads to a ratchet effect that left leaning things are "political" but discussing current events with a conservative slant isn't. Literally just a mirror of life in the US
A chud has to be very far gone to actually bother to try to get one of those. They aren't exactly easy to find, even in chud areas, so that's some serious virtue signaling there.
Weirdly I was also thinking of CS folks. I think the entire CS community is closeted hitlers, but there is enough money in the scene that the ones who let their Hitler particles fly are removed. I'm thinking of Thorin and Sado, RL to some extent, Redeye by some accounts, and others that you mentioned here. And then the owner of G2 as well got the axe for being sexist. There have been others too.
If at the very least they can't use their platform to spread the hate I guess that's a better outcome than it could be. At least within the "official" scene of paid tournaments.
