Ehhh, Amazon offers a hosted Grafana service, which is AGPL. I'm not so sure that.

Which means that they have to share their changes to Grafana, doesn't it?

The LWN thread says that they don't, but have separate proprietary licensing and co-marketing agreements with Grafana Labs.

Thanks that interesting!

And in this case it means that it's not AGPL, but proprietary. Which kind of proves my point: they are apparently paying Grafana Labs to avoid the constraints of AGPL. If Grafana was permissive, they would surely not pay.

That's not what I'm getting at.

Amazon hosting Grafana means it's not only "permissive licences are better for competitors".

Copyleft licenses don't present obstacle to competitors that people seem to believe.
