GitLab is not open source though. They call their approach "open core" which imho is just a marketing gimmick to appear as an open source solution when in fact they are not fully open source.
I am not a big fan of GitLab-the-company. But GitLab CE is licensed as MIT. You can do with it what you wilt.
I have a hunch that your actual complaint is that they too do with it what they wilt, and what they wilt is not "give to you everything they add on top of GitLab for free and forever".
Yes. That's what I meant, but also I don't think that's a bad thing. Building software is hard and expensive. I think is valid to only open source certain parts of your system and reserve the right to monetize other parts and features.
Good point. I'm not criticizing. I'm a very happy GitLab customer and love what they do. But just wanted to point out that they don't call themselves "Open Source" and their business model is not necessarily an open source first kind of business.
