Are they actually growing much more in the mindset of developers since GitHub started doing some things right?
I have personally always wanted alternatives and GitLab* is a good one, but the reason I can not say they are a great one is because somehow* their story to me feels too much "against GitHub" than their own story.
GitHub made a lot of mess and eventually they undid some or just enough that they still retain the lion's share of public repos/projects. This matters a lot because community is great power, whoever holds it, holds key to future mindshare.
I want GitLab to be a larger part of the developers mindset everywhere, but I am not sure that is happening at the moment. Why not? If my assumptions are wrong, that is also acceptable to me, would like to see some signals.
