Not mine but sounds like a showerthought to me. TL;DR ChromeOS is the “wrong” version of Linux and has 4% while GNU/Linux has 3%
Windows is also ridiculously good at backwards compatibility. Mac frequently just breaks old software and Linux is largely unconcerned because they assume anyone that cares will find a way. That backwards compatibility is over of the major keys to Windows success with developers.
But Linux is good at backward compatibility tho. Linus Torvalds leadership made sure that very few if at all any changes to the kernel will break existing userland. This means that if you have a program with their needed dependencies in the right version (which is easy with docker/flatpak/appimage) your programs will run flawlessly even if they are from the 90s.
