I just wish more developers could follow Grafana's path and switch to the AGPL when that becomes a problem, instead of switching to fauxpen source licenses.
They are explicitly not a charity. Isn’t it okay to be a for profit company that sells software with a closed copyrighted source?
If Red Hat could change the license, would they? Maybe. (Not now but you can’t say the leadership won’t make that decision during financial crisis).
That there's freeloaders that benefit from the work without having to expend labour is a side-effect, not the primary motivation.
Chosing to release software under a non-FLOSS, proprietary license is hardly innovative, and I'm afraid trying to frame it that way sounds like you want to have your FLOSS cake and eat it too.
