I get why GitLab wrote this, but it seems like just a stab at GitHub.

There seems to be a lot of hating on GitHub here, but I personally love GitHub (and we use GitLab at my current employer).

I think GitLab is doing a great thing, and I appreciate that their community edition is free and open source, but GitHub has been able to provide an invaluable service. They have a great community that facilitates open source projects and a vastly better UI than GitLab (though that isn't saying much with how awful GitLab's UI is).

I'm eager to see how GitHub evolves in the future with GitLab as a competitor, as GitLab has a lot of nice features (built-in CI, etc).
