Er, if you develop the infrastructure to host MongoDB, you should absolutely be able to open-source that infrastructure. I mean, before MongoDB, I wrote a cluster management system for virtualized software security and hypervisor research, and all of it was either open source or something I wrote…

Also, if you bought something closed-source to sell MongoDB as a service, why isn’t it realistic to buy a license?

Your suggestion of a monopoly in the DBaaS space seems to preclude the existence of other databases… Or am I misunderstanding?

I’m not sure what you mean by “IT is a business decision” — could you elaborate?

-edit- P.S. I’m trying to be supportive here; not trying to take anything away from what you’ve built with FerretDB! Honestly, there’s room for so room for innovation in this domain, and it’s nice to see new projects…
