So we are at the point where American video game developers are banning people from e-sports competitions for their comments over a domestic issue in a foreign country? Because the Chinese government probably didn't like his comments, that counts as 'public disrepute'? This is just wild to me.
It is wild, but it's also part of their own rules:

Yes. You presuppose that all rules - via their nature of being rules - are automatically fair. They aren't. Especially not if they're not arrived at by consensus, but unilaterally laid out.
Creating rules by consensus is actually a terrible way to ensure that those with views counter to the majority are treated fairly.
