The funny thing to me, which I haven't seen anyone else mention yet, is that way, way back in the old days, Grafana started out as a fork of Kibana. Go take a look at the first commit in the Grafana source: https://github.com/grafana/grafana/commit/75d03fc49ab4f95ee4... Anyone want to guess what the third commit was? That's right, it was an Apache 2 license: https://github.com/grafana/grafana/commits/master?after=2bb…
What do you mean? Any free software licence allows forks, including AGPL.
Their FAQ even says:
> I asked Torkel, and he said that If Kibana had been an AGPL project, Grafana would likely have been AGPL from day one.
