Git is a registered trademark of neither GitLab or GitHub. Both GitLab and GitHub have negotiated the usage of the Git trademark. Provided they follow the rules set out for them, they can continue to use it.

As an employee of one of them I personally bought the git.new domain. I paid a good chunk for it and was going to build a new project template builder on it. I got.. talked too by legal about this. Because as an employee it actually violated one of those rules.

So that’s the how, and why I know.
