I used to think this. But with so many Linux variants out there I think supporting it is harder than just supporting the windows api that makes it work.

It’s odd but things like docker and the JVM and browser based software mean the software will run abstracted a bit, less optimally, but good enough. Even among the different Linux distros software is distributed differently (rpm, debs, flat pack, pacman….)

Brining more people to Linux is the goal, more developers! and better software packaging eventually.
