I learned to code by modding Minecraft, starting at ~1.6 a few years before the Microsoft acquisition.
It was definitely already obfuscated by then, the Microsoft acquisition had nothing to do with it.
If anything, looking back all the years, Microsoft has largely delivered on the promise to not fuck up the game and its community. They’ve mostly kept their hands off it, besides the Microsoft account stuff (which makes sense why they did it, but a lot of people are still understandably annoyed). Hell, they’ve kept up two separate codebases in fairly close feature parity for _years_. I doubt they’d have kept JE if there weren’t people in that team who genuinely cared.
