There’s a bit more community contribution that just “code”. I have never contributed code to elasticsearch, but I have co-founded the Berlin ES meetup, before elastic, the company, even was a thing. The group was for some time one of the largest around. For a while, I was one of the most active posters in their IRC channel, helping other users with whatever issues they’d have using ES. I signed no CLA, I received no money nor do I want any. But I contributed my time in the understanding that we’re all working on something that benefits both ourselves and the wider community. That implicit understanding is now gone.
