Learning any OS isn’t a trivial task, but that’s something people seems to forget a lot.
But I get why people would say “just use Linux”, because if by chance you have the means to switch then why would you still stat locked to a tool made by a company that doesn’t care about you or your needs ? It would be counterproductive. (Also getting more Linux users would be beneficial for the Linux community, it could even be beneficial to everyone if that number is big enough to make Linux a serious competitor)
