I see what you mean. Yes there are great examples like those that offer support contracts for the open source software projects.
I think one point of confusion here is that as open source licenced projects, they do not restrict commercial use. The companies that lead the development just happen to also offer the best paid support.
Minor correction: proxmox is AGPL so free to use commercially without their support contract.
i usually advocate for a more restrictive license for commercial use, to avoid openssl type situations. where huge corpos will take it, use it to build big infrastructure without compensating the creator at all, and not even bothering to help with maintenance.
