I would love to make the source available. But there's no getting that genie back in the bottle once you go that route. I wanted to release it and get some feedback before deciding what to do with it. That said, a server that supports the examples on this page is pretty trivial to implement (especially if you skip the pubsub stuff). I had a working prototype in a weekend. Multiple implementations would probably be a good thing.
EDIT: also, the current state of the code base is not something I'd be excited about having my name attached to ;)
You can think about releasing the code with no license or with some form of the newer BSL or something.
It won't stop bad actors from stealing your code and using it but you will stop most corporate actors from touching it (and they are the ones you'd want to pay in the future anyway).
