If you think you were burned out before, becoming an open source maintainer probably won't help :) If I were you I would put out a call for maintainers, and maybe consider a license that keeps modifications open source. That way a company that modifies it will have to contribute back to the project. If you do open source, I recommend moving your roadmap to a GitHub Project, put together a contributors guide/agreement.

Companies will definitely be averse to using a project due to trademark or licensing issues. Apparently somebody is using the name (https://alter.com/trademarks/glue-85698439). You could probably find a way to signify your use is distinctive from that other one, and you may want to register it to protect it. IANAL.

I think it has a lot of potential, but finding people who want to build it out/run the project will be the challenge.
