I'll try to answer this from a consumer point of view. It makes a ton of sense for a startup to do this. As a potential client of this, I may end up liking it a lot but worry if this company is going to be around in a year. Open source means that if I HAD to, I can run it myself. That said, our company would rather not run it ourselves. Managed services, SaaS, etc. are ideal for us. So being more permissive and a managed service/SaaS is the best combination for us looking at it as a potential customer. If this gets super popular, it's likely that the existing customers won't want to switch even if someone else offers it.
