I've never played #Minecraft - Is this #Federated software? Is it #FreeSoftware? If so, how can Microsoft control what's happening on someone's private server? Even if such code existed in a #FreeSoftware application, I would have thought there'd be a fork that eliminates that external control. It's time for that now.
But if #Minecraft isn't #FreeSoftware aka Free/Libre Open Source Software, then I really have no sympathies for people running or using it...
