You might want to consider just open sourcing portions of your code that you believe could benefit from community involvement, and keep certain things proprietary. If that is an option you could have separate repos and publish the ones you want to share.

If that’s not an option, it may be that opening up the code doesn’t fit your business model

Yeah, that's exactly what we have in mind, the core source code is available to anyone to utilize for any commercial purposes except providing mass hosting for the source code without any substantial development/customization. Do you think this restriction will prevent people from using the software?
