One of the things I really considered is that if nobody gives these "independent" Linux-focussed vendors a chance, then Linux-on-the-desktop will forever remain a non-factory option and a second-class citizen in support manners.
Linux will never be a mainstream option with these low effort products.
Evidence so far indicates that they do not, when given the chance.
Dell and Lenovo generally do a pretty good job, and those machines sell well, but I think the quality is still below what, say, Apple can deliver. Judging by the push to get Linux to run on Apple hardware, I'd say Linux enthusiasts are not only willing to pay a premium for a quality product, but willing to invest time and effort getting it to run well in a hostile and closed ecosystem.
So I think there's a big market opportunity for someone to deliver Apple quality hardware, that integrates well with open source software. Framework is probably at the frontlines in this regard.
Framework is probably an exception but I wouldn't be surprised if the majority of those who bought it still use Windows
I've said it before, and I'll keep saying it: the smartest thing Apple ever did was keeping you from running OSX on Windows computers. Nobody buys a commodity PC, slaps OSX on it, and expects it to work as well or better than Windows. Yet this is how many do Linux.
