Microsoft is adding the capability for their moderators to completely ban you from multiplayer minecraft. Why do they think they should moderate who gets access to my servers?
It could be that you have the wrong politics, or wrong anything else that is arbitrary and capricious. We've see exactly this occur in the last decade so NO ONE can be trusted to have centralized control like this.
It does make me glad I never jumped onto the Minecraft bandwagon - I have no investment of time or passion to lose from this.
