I can't speak for every single one of them but I can say that some of them probably did it by choice and was prepared to handle the friction in the beginning until they get used to it. I know lots of people who switched from Windows to Mac where power users / had good computer habit.

However, I don't think some of the older people are willing to go through all that. I wish to see an easier option for people who wants a smoother transition from Win10 to something else, especially now since Win10 is being discontinued october this year.
