No company (or academic institution) I've ever worked for developed _anything_ on MacOS. That's a US-only phenomenon, I think.
The thing about Android, it was essentially foisted on people, not chosen because it just works. Also, many Linux distributions today "just work" on typical hardware - almost as well as Android on your phone. And if you were using a hardware config chosen by someone else, and a Linux-based distribution pre-installed and pre-configured for that hardware - then Linux very much "just works".
It is true, though, that this is not enough to expand the user base far enough. That needs a lot of coordinated, collective, public activity.
