Linux isn’t ready for the mass Market yet. I say that as someone that has been a Windows free household for like over 8 years and who actively attempts to convert as many of my friends as I can.
It is not and probably never will be general market ready. Too fragmented and too many options. Which is why I love it so I wouldn’t want it to change either.
I’m not sure what universe you live in lol. Yes lots of people like mint but plenty hate it. I don’t hate it but it wouldn’t be/hasn’t been my recommendation when converting people
