It was bad enough having to pay twice for the same game (java edition, then bedrock edition, as some of their friends could only play the microsoft edition on their Nintendo Switches, etc).
But if microsoft cause the 3rd party ecosystem of servers and mods to close down forcing everyone onto microsoft servers, I will ban my kids from playing at all. Quite sad, they and their friends have grown up with minecraft, it's almost the lego of our times, with a dose of capture-the-flag, though my kids also have lego and play skirmish irl.
That being said, if you're banning your kids from playing Minecraft because Microsoft Bad, that's just shitty.
I'm maybe being a bit dramatic by saying I'll ban them, but they will certainly be given a lesson on taking a stand, and if necessary making sacrifices, to defend freedoms and not give in to coercion.
It's not at all 'microsoft bad', except in this case, it seems they are.
