No, it demonstrates that things that the Linux kernel adopts tend to get adopted. That isn't very surprising. Git being faster than the dVCS's of the time probably helped. Popularity doesn't equate to quality. QWERTY is still the default keyboard layout.
I am willing to bet money (let's say 0.1 bitcoins) that there are plenty of people at your university who have trouble with Git. We can haggle on terms, but I'd bet that you'd see 10 people at least struggling with git in an intro course.
Once you learn to give it the right incantations, and learn never to deviate from the path you know, any tool can become usable. But it will never be a part of you and will never make you stronger.
This has crippled a generation of developers and I'm afraid it will be a massive barrier to entry, stunting humanity's growth probably by 10-20 years.
