I don't actually like many Open Source "products". I like a lot of Open Source and Free software, but trying to turn that stuff into a product almost inevitably ruins it. Just look at Plex, or NextCloud, or Docker, etc..
Open source can either be sponsored, have a Cloud version or ask for support fees, isn't that the natural transition for an open source product?
For the best projects, like Open Source operating systems and programming languages, no.
