That's great for hobbyists and tinkerers, but when Joe Schmoe off the street thinks, "man, I sure am tired of the full screen unskippable ads in Windows 15", he's not going to follow that up with "I guess I'll go buy a low power hobbyist board to tinker with an alternate OS for nerds". Whereas today you can still just install Linux on the same laptop you're already using, and sometimes even Joe Schmoe off the street does just that.
