Dumb enterprisey 'certification' aside, I can see the free course being effectively used during onboarding (esp. intern/grads, but anyone can not have used GitHub or even git before, just because it's not what previous employer used) at which point being 'certified' becomes a handy 'get out of going through that again' card...

At least at the university I went to we had multiple classes that required using git and plenty of freshmen came in with at least a basic understanding.

Yeah of course, or one might have been contributing to the Linux kernel since age 12, had internships or worked on open source as a hobby.

But not everyone, and even if so, there might be value in ensuring a base level understanding of 'use of git & GitHub', especially if you happen to do it in the GitHub proscribed way.

I'm sure many organisations have worse/more obvious/less worthwhile-as-viewed-by-new-hire on-boarding to go through!
