The first point covered, giving away your core IP, is definitely one that resonates with me. We went open core with our headless document management system (https://github.com/formkiq/formkiq-core), and there is always a worry in the back of my mind that we are providing such a solid foundation with the open core/source components that we may be undercutting our enterprise modules.

But on the other hand, I don't know that we're popular enough for someone to come along and build free modules on top of our product. So maybe this isn't a problem we'd need to worry about.

Until it is... ??
