The most controversial change, in my opinion, would be ending support for playing older versions of Minecraft.
One of the reasons players love Minecraft is that they can play any version they want, for as long as they want. However, with Windows 11 succeeding Windows 10, and newer operating systems doing so in the distant future, Microsoft/Mojang will face a dilemma, that what worked on Windows 7, may not work for Windows 12, 13, 14, etc.
So the corporation would have to make the hard decision: to end support for older versions of the game.
One example is the use of emulators people rely on to play Minecraft on ARM-based Apple MacBooks. Native support only starts at 1.19.X, so anyone wishing to enjoy 1.12 nostalgia will be disappointed. Why someone wants to play Minecraft on a Mac is beside the point. The fact ARM processors cannot natively run older versions, which were meant for x86 architecture (for engineering-related reasons) creates an issue for players who were used to Intel-based MacBooks, which can play those versions natively. This isn't too controversial, because most people play the game on Windows, but also players use emulators, though at the expense of performance.
I enjoy playing version 1.16. I'll be sad if support ever stops, though that should be a very long time from now.
