This is an interesting situation for FOSS licenses. AGPL doesn't necessarily prohibit commercial behavior. I think if all the maintainers truly wanted to prevent anyone from commercializing it, you'd go with a source available license like BSL or creative commons.

It's interesting because having a group of disparate humans come together and say "yea, we hate the current thing, let's build something better and not commercialize it" doesn't typically happen. Kudos to you folks!
