MS really hates minecraft's inherited self hosted server model. You can actually get a global ban for wrongthink commited on your own private server. (granted, someone needs to report you but still)

Also not really a censorship issue but I'm kinda bummed that the new version will default to having the server whitelist on. Going on an ip scanning site and joining random minecraft servers accindentally left on for years is an experience like no other. Some of the longer running ones are full of signs left by other explorers, or just griefed to shit. One of the few remaining wild wests on the internet.
