The GitHub terms:

> You must be age 13 or older. While we are thrilled to see brilliant young coders get excited by learning to program, we must comply with United States law. GitHub does not target our Service to children under 13, and we do not permit any Users under 13 on our Service. If we learn of any User under the age of 13, we will terminate that User’s Account immediately. If you are a resident of a country outside the United States, your country’s minimum age may be older; in such a case, you are responsible for complying with your country’s laws.

This is far more likely to be the reason than using Linux over Windows, lol.

I am using GNU/Linux on a bare machine. I started using GNU/Linux when I was 9.

Sure, but in the US children under 13 are more often than not banned from using internet services due to an ill-conceived law called COPPA.

He didn't mean you were running Linux "on" or "under" Windows. What he meant was "this is not because you are running Linux instead of Windows".

If you’re calling it GNU/Linux, I believe you.
