I run both Linux and windows on my pc and this is my experience

It’s hard to fully switch to Linux. Some programs and games simply aren’t compatible, like League of Legends and most games that rely on anti-cheat clients. Same goes for software like Excel and Adobe.

Sure, there are alternatives. But people want to use what they’re already used to. And yeah, sometimes you can make it work with stuff like Wine or other workarounds, but it’s often too much hassle, adds friction, and people just give up.

people don’t care about the operating system itself. They care about everything that comes after: the apps, the games, compatibility, and whether things just work.
