Does it matter? Generally Linux desktop distributions are made for the people who use them, who would tend towards people who will fix things. You mention distros but there obviously are a lot of passionate distro makers because right now it seems like there are more distros than ever.

There are often comments on threads like this that go along the lines of "If only the people making Linux desktop did X then they'd get more people". But there there isn't really anyone making Linux on the desktop. It's not a product. Even the products within it are built on the work of people with very disparate interests. It's kind of amazing that we get a cobbled together working experience at all.

Apple and Microsoft can focus on particular things, like getting more users, or supporting hardware they want to sell, or trying to get you to sign up to Office 365. No Linux desktop environment can have that kind of focus. So when you say it's not fixable to most users I think: well it's not supposed to be. It's not supposed to be anything, it just kind of is. Like coming across a mountain instead of a theme park - it's not a curated experience, it's not going to be for everyone, you might get hurt, but it's far far more beautiful.
