Because although sometimes annoying, people already have a good alternative making the hours required to invest in something they're not interested in a very high price.

It's the same reason why as a software developer I use Visual Studio Code and don't plan to learn (neo)vim.

I (like many who'd have to learn Linux) have better things to do.

You simply dismissed or forgot the learning you did to use Visual Studio Code.

Regardless of how much learning you did you still had to learn how to use it.

Just trying to short-circuit that logic and show you that it cuts both ways and that we should be willing to learn new tools.
