On this day in 1991, Linus Torvalds announced he was working on what would become Linux

This is a most excellent place for technology news and articles.
That argument falls a bit with the Steam Deck. Linux is preinstalled and most people don't change the OS. On the other hand it's purpose is also pretty specific, so it isn't an issue if Adobe's softwares works etc.
But people are happy with ChromeOS, which is limited but preinstalled. So I do believe preinstalling makes and fails an OS. It's not even worth it for some car manufacturers to have different skews for chair heating, so it's not surprising that pc/laptops don't come with choices between different OS.
I'm happy with Linux, but I don't think most people want what Linux gives them. Most people just want to stop using it and do something fun.
