MS has inertia on its side, and its abusive marketing and lock-in strategies of the 90s. Remember when you couldn't buy a PC without Windows from most vendors? Meaning you were paying MS, even if you immediately uninstalled it?
The long term outcome of that is that 90+% of industry still buys Windows PCs. And non-industry: once non-techie people are on an OS (Windows/MacOS), many don't move off it, though Apple's ecosystem has been a good carrot+stick.
One of the more interesting indicators is (even though desktop software is in decline) - the number of apps that are Windows and Mac and maybe linux, and the increasing number of apps that Mac-only or Mac+Linux but do NOT have a Windows download. Something unimaginable in the 90s and 00s.
MS are certainly accelerating adoption of other platforms due to their own mismanagement.
I just realized, when I got my HP laptop I've never even booted its default Windows install, but MS still got paid. I'd rather have that money to go HP so the laptop could be made better. Insane how they're getting paid for nothing, almost like a tax. HP could just have offered an OSless option, but no. A silly world we live in.
It still can't be a PC without windows, when going to the shopping mall stores normies use.
The computers on display are gaming PCs with windows, PC laptops with Windows, macOS laptops, and Chromebooks, which in Europe are largely ignored.
Normies aren't going to Tuxedo website asking for a Linux desktop.
