GitLab acquires Gitorious

I'd say that they want to demo the full feature set to potential customers instead. They rely on selling their stuff, so they need to show off what they can do.

Plus many of those features are about making it easier to manage a large scale installation, so it would be kind of stupid not to rely on them on the (I would guess) largest installation there is.

PS: The community edition does run well, too:-) I use it on a small server at home to host a couple of private repos in-house.
