People leaving Windows en masse needs three things:

1. Continued enshitification, which will likely continue.
2. More apps (games, productivity, etc.) having native support for Linux, or at least a viable alternative.
3. Linux devs to prioritize user friendliness over gatekeeping/"just use macros" mentality.

I'm heavily thinking on moving to Linux in the future, likely when I'll need to reinstall my OS. Then I'll only keep around Windows for testing purposes.

EDIT: I wrote two instead of three
