Minecraft wasn’t built as a kids game. It was a neat indie game that let you build stuff.

On kid-specific servers that might be an apt analogy, but adult-owned, adult-populated servers shouldn’t have to worry about malicious trolls ruining their experience with a ban.

Nope, not at all, because it applies to privately run servers. It's the equivalent of breaking into my house and stealing my Legos, based on somebody's statement that I swore around children who happened to be near Legos.

I bought Minecraft in 2011. Every few years since then, I would get friends back together, host a new server, and catch up while playing. I bought the software, I host the server, I ban people if need be, and how dare Microsoft treat it as their walled garden.

Sure, if every group of friends had their own tiny version of Legoland and Lego corporate could ban you from all of them.

It's more the equivalent of getting banned from driving because someone reported you to Honda, and Honda didn't verify anything.
