Unfortunately. It's too bad that it don't focus a bit more on the ideological philosophy of GNU, even if, as far as I know, Torvalds don't care much about it.

Unfortunately. It's too bad that it don't focus a bit more on the ideological philosophy of GNU, even if, as far as I know, Torvalds don't care much about it. Especially for those who would like or dislike the ideology: those who disagree or for whom it don't make a sufficient reason to use it could get away from it, those who don't know could be attracted. In my personal experience, the ideological aspect is 90% of why I use GNU and Linux, and when I see all the people running a GNU/Linux desktop inside or outside the tech communities, I don't really agree with the idea that it "never became a significant presence on mainstream desktops". It does became mainstream for people with specific uses for various reasons (political, technical, ethical, etc.). For sure, it never became mainstream in supermarkets.
