Why do you think they do? Logically think it through.
Market sharen and incumbent advantage. Ease of adoption (or appearance of). Ubiquity and lack of need to retain. Predatory behaviour by MS. Different priorities for users.
Unless you actually consider the real reasons why Windows is so widespread you'll never make a dent in it.
Thank you for acknowledging that point. Because since Win7 or so, Almost all major Linux distributions are shitloads easier to learn that any windows environment, no matter how unfamiliar you are with Linux.
Basically, all major desktop environments behave like an optimized WinXP desktop.
let me be the one to say: the only people who "need" VR are those earning their money with selling VR products. No one else in the whole wide world actually needs VR.
There's a lot of stuff everyone has that they don't need. What's your point? Are you going to go vegan? because technically you don't need meat. Are you going to stop driving an automatic transmission? Because you don't need that. Oh, social media (Lemmy included), you definitely don't need that.
So how good did I think my point was?
VR is an artificial hype, especially in a time where almost all major game releases lack in story and already put way too much money into graphical effects. It's a gadget.
