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 (<a href="https://github.com/formkiq/formkiq-core" rel="nofollow">https://github.com/formkiq/formkiq-core</a>), 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.<p>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.<p>Until it is... ??
