This is the kind of pessimistic take that gets a lot of traction on HN, but man does it not match my experience.
> Minecraft mods were how a lot of teenagers got acquainted with scripting, and it's a lot harder to get started with your own server since MS bought it and forced it to authenticate through Azure.
First off, the pivot from mods to running a server is sort of related, I guess? But it's not at all clear how your complaints about servers have any bearing on the modding, which is still very much there. The Minecraft Forge docs are better than ever [0], there are 3000+ mods on Curseforge already compatible with 1.21 and 5000+ compatible with 1.20. That a lot of kids have moved to other games has more to do with the ephemeral nature of childhood entertainment than it does with Microsoft stifling modding in any way.
Second, I'm not at all sure what you mean about servers being harder to set up. Here are the instructions for setting up a Minecraft server [1]. The instructions actually seem substantially shorter than I remember them being from back in the day, most of the bullet points are just explanations for various settings you could configure. (EDIT: Just to be sure I decided to try it myself and got a server running in just under 5 minutes. Obviously your average kid isn't going to be able to move that quickly in the terminal, but there was no authentication step.)
> It's nice that they've added a bunch of functionality, but the pessimistic view is that MS spent $1.6B to force the world's schoolchildren to make office.com logins.
Microsoft bought Minecraft in 2014, 3 years after it was officially released and 10 years before now. What you're offering is a very pessimistic view given that history, especially so given that it seems to be entirely based on a single account migration from bespoke Minecraft accounts to Microsoft accounts. You can be cynical about that all you want, but speaking is a developer in a company that currently has 3 account systems I'm going to venture that that move was exactly what they claimed it was: an effort to simplify things and increase security.
