IIRC EnterpriseDB mainly makes it money from paid hosting and I think Hashicorp makes its money from a combo of paid hosting and open core (i.e. it has other proprietary tools and add-ons). SUSE is a good example, but I'm not as sure about Canonical. Wasn't it the case that Canonical is actually operating at a loss and has been for a while? Maybe that's changed?

Canonical had a $20 million operating profit in 2020.

Oh interesting. But digging into that it looks like it's coming from adding open core and previous to that they were losing money? (Ubuntu Pro + Ubuntu Advantage providing auxiliary proprietary? tools)

But then you can argue that RedHat made also money with Openshift no?

>EnterpriseDB mainly makes it money from paid hosting

Not sure if that's true.

> But then you can argue that RedHat made also money with Openshift no?

Yeah but RedHat's (and I guess SUSE?) miracle is that they were still very profitable before Openshift.

Well hopefully someone from EnterpriseDB can chime in!
