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.”
There’s another thing that frustrates me about Linux and its various philosophies. Should I be allowed to do what I want with my software? Or should the machine protect me from myself? It seems at conflict with itself to allow you to do stuff like delete system files without much more than a warning while also having protections in place as you describe. Windows tried doing this exact thing with S Mode and people get pissed about windows not allowing them to do whatever they want.
I fundamentally disagree that users should not be allowed to install whatever they want from wherever they want.
You can install whatever dodgy file from wherever you want. I (and many others) don’t think that should be the default
