What makes Windows a “bad” OS? Why does the computer science world force Linux on you?

I have worked on linux in school and I don’t hate it but I don’t see what it has that windows doesn’t (so far). The differences I do see on linux are manually done things, things that are automated on windows. Besides being free and no viruses(because I have avoided viruses my whole life through smart web searching/downloading) what are advantages over windows? *Also why can’t a computer scientist like me fix the problems windows does have*? I mean isn’t that the purpose of my degree? I’m sorry if I sound like a windows fanboy but I just want a totally performance/convenience based reasoning.

*I know windows is closed source but let’s just say I mean to join Microsoft and help fix it*
