Universities have been running Linux since the very early versions. Slackware was pretty common back in the 90s and 2000s and universities had labs full of them not least because there weren’t really laptops so they had to have enough machines for all the students. Universities have been heavily involved in the development of unix from its inception and a lot of the tools were initially written by university professors.
I sub to channels and use Youtubes recommendations and new for you to find additional channels etc but I don’t watch them I use Metube and a browser plugin and download the videos to a directory. I don’t get all the privacy but I also am not giving them much watch data and I can avoid the ads.
