I'd imagine that, as people in poorer regions in the world get access to laptops, we'll see a big increase in free operating systems. Sure, you could crack Windows, but why would you? Windows 11 isn't really good, and cracked software gets no support. Might as well go for a legal Ubuntu with lots of community support and decades of online help for all possible issues. It's a modern OS nowadays.
The real question should be: would most developers WANT to use a Mac, if given the choice?
Personally, I think OSX is the superior of the two simply because it's stable as can be, takes no (and allows almost no) tinkering to get working. Controversial opinion, I'm sure.
