Hard to tell, but from my(developer) point of view I see it as a big benefit to be able to see the code. Plus it gives me the option, in case I like the service and it is discontinued for any reason, to just host it by myself. Also it adds another layer of trust and I have the feeling I can influence the product.

Definitely, I think Ghost is a very good and successful example of Open Source SaaS.
