That said I do hope you take steps to reassure people who want to be using an option which preserves their software freedom, for example that the CE will not be slowly deprecated, more features moving into EE.
I admit that making a fully credible commitment is challenging: options include multi-copyrightholder-copyleft which presumably you don't want at all as an MIT licensed project + some proprietary bits in EE, and a variation on the Fiduciary License Agreement used for Qt. But those two options are copyright-focused; there are probably other mechanisms to be thought of.
Recently Gitlab CE has undergone some quite significant UI updates along with very noticeable performance improvements. Excellent work guys!
Signed: a very happy Gitlab CE user.
But adding more features to the open source version every month is great. Hopefully that and a massive userbase sums to making it obvious that any substantial move towards deprecating the open source version will lead to a successful hostile fork, as there will be tons of people able and interested in doing that if necessary, resulting in you never making it necessary. :)
It is sad that enterprises are confused by freedom rather than demanding of it, but that's an issue for the software freedom movement to solve.
On another note, https://about.gitlab.com/better-than-github/ is a well done page. I wish you maximum success.
And yes, the huge community around GitLab will ensure a fork if we turn evil and start crippling the open source version.
Glad you like our comparison page with GitHub :)
