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.”
For years and years the barrier to entry was mom or gramma buying a clipart CD for $4.99 at the grocery store, bringing it home, and expecting it to work.
Now that’s not a thing anymore, but they still aren’t using it. So I guess the barrier to entry now is they see that ad for the casino app that “pays you real money” and they expect to download it and expect it to work.
Until mom and grandmom can load up the computer with all sorts of malware that breaks everything, they really aren’t interested.
