Like most things, "Open Source" is relative and spans a gradient. It can be open but undocumented, it can be open but with closed components, it can be open but broken, it can be open but closed to outside contributors, and so on. The most important question is whether it's forkable? If X decided to go against its community, how painful would it be to fork X and for the community to continue without the maintainer's support? Is GitLab more open source than GitHub? Absolutely. If I committed substantial resources integrating with "the GitLab way of doing things" and then GitLab pulled the rug on me, would I be able to retain my investment by forking off the product? For most things, yes. I'm all for GitLab becoming even more open source, but they deserve the accolades they've gotten so far.
