Most people had never even heard of Linux. It has taken a lot of very bad things on Windows for it to get to this point. It’s classic frog in a slowly heating up pot territory.
My experience is that people fear linux, rather than not knowing. I am the lonely Linux user since c. 2005, and people see half my screen is always a console, the other half a browser. So they fear linux is for console wizards, not for regular users. Nothing will convince them otherwise, even when they are 100% of the time using online webapps. I have some coworkers using browser + VS code + WSL2 all the time, but they don't switch because they fear the console-to-config-everything instead of Control Panel.
