Have you ever considered using the AGPLv3 for the Community Edition, rather than the all-permissive MIT license?

I'm pretty sure they take outside contributions for CE, so if that was AGPL3 they wouldn't be able to use it in Gitlab EE, which sounds like shooting themselves in the foot.

They could require a CLA for outside contributions. Many organizations do that.
