I feel that people still need to support Windows for a while. I for example am stuck on Windows because it (still) has the best accessibility out of all of the operating systems (and Wine is not a replacement for that). It's unfortunate, and I'm hoping it will change in the future.
I’m surprised to hear that, I don’t often use accessibility options on Mac but i use some on iOS so I always assumed Apple had the best a11y since there are so many options on iOS. Like almost too many, though I get that’s kind of the point.
