Reading about FOSS philosophy, degoogling, becoming against corporations, and now a full-blown woke communist (like Linus Torvalds)
In my experience I've noticed Linux tends to (disproportionately) attract both libertarians and socialists/communists. I feel like I run into more of both within the Linux community than I do in other communities.
I started using Linux because I couldn't force myself to use Windows 8. Up to that point I used whatever version of Windows came right before the graphical interface but 8 was too awful so I started playing with mint and never went back..
I got off the capitalism train in the middle of that but that was only because I decided to major in business and when I saw how the sausage was made I jumped ship but I didn't know anything about socialism or communism or marxism or whatever you want to call it. I was so not into politics or economics that I literally had to search the Internet and ask people on social media what was an alternative to the crap I was reading for my classes.. And then I went down that rabbit hole. If was enlightening. I learned a lot.
Also... for people who think college is Marxist indoctrination...Marx was brought up for one paragraph in one book at the very very end of my 4 years. But by that point I already knew who he was just from the rabbit hole I went down when I was curious for some alternative to what I was being taught.
