As Torvalds pointed out in 2019, is that while some major hardware vendors do sell Linux PCs – Dell, for example, with Ubuntu – none of them make it easy. There are also great specialist Linux PC vendors, such as System76, Germany’s TUXEDO Computers, and the UK-based Star Labs, but they tend to market to people who are already into Linux, not disgruntled Windows users. No, one big reason why Linux hasn’t taken off is that there are no major PC OEMs strongly backing it. To Torvalds, Chromebooks “are the path toward the desktop.”
Like mentioned in the articles, another issue is that there are very few offerings of computers with Linux preinstalled in normal computer stores.
You know how a normal average persons buys new laptops? They go to such store and look at the prices and buy one according to how much they want to spend. The advanced buyers might consult their more tech-savvy acquaintances. Stuff like “Just install Linux”, is beyond concept comprehension for a lot of people, even if they heard about Linux at all.
All to say is that it’s not like they can’t understand these concepts if you explain them (people are clever), but they should care about them in the first place.
