I think the one criticism is that it seems the company has some intentional rough edges on it, in favor of their SaaS over the open source release. It used to be around backing up and managing updates long term ect. They have gotten better but their helm chart for example is very opinionated and uses custom resources in place of say a statefulset. I think their SaaS is overpriced especially compared to reserved instances but that's just me.
Also from my calls with support, they lack direction internally. One time our sales rep and customer success director argued on the phone in front of us if they could bill us for some migration work. We silently let them finish and then said we expect it to be included in our support package based on their argument.
