While I think I get what you're trying to say, I don't think it's necessarily unusable for regular users, more so unreachable in a nice, preinstalled form from a well-known brand & retailer.
Also, there's no ads for GNU/Linux machines on TV or on the Metro, which I think is often underappreciated.
I know because I've personally witnessed friends and family members who swore Linux is unusable give it a serious try only after Windows or macOS crossed them for the nth time and haven't had a single one switch back.
The key is to get hardware that is well-supported and not 2nd tier i.e. not a netbook etc. that I'm just going to throw Linux on and compare the experience to my 10x more expensive MBP.
The experience's not perfect, but that's not the case for macOS either. Is it "unusable"? Far from it.
The key is to get top-class hardware with the express intention of it running Linux, rather than installing it on the laptop Windows will no longer run reasonably on.
It is true however that such as switch is easier for developers like myself who are not dependent on Cocoa/SwiftUI etc. but that's a choice you have to make.
