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.”
I’m not sure oem adoption would make many people migrate. Here in Brazil, it’s a common practice for oems to sell computers with linux, and they cost cheaper, with the same hardware configuration. The result: people see them just as a cheaper option and ask their Tech Friend™ to install a pirated windows for them.
I don’t think that people don’t make tech choices. They actually choose windows, and will find a way to have windows, if it’s not a default. People who use linux do so mostly as a choice, not simply because it came installed.
