@rysiek It might be too commercial to fit the pattern you´re looking for, but:
The company I work for is running a massive internal GitLab platform with ca. 40.000 users.
They´re using the community version. If there´s a feature they need, they build it and contribute it upstream, where it becomes part of the community version.

This isn´t done for charitable purposes. It´s done because it makes good business sense. #FLOSS #FOSS
