This is a quote from Jeff's response:

"To be crystal clear here, our intentions are that we will not charge for development that happens under the “App Explore” product (i.e., the free version). Usage of the Appcelerator platform (Titanium Mobile SDK, Titanium Studio, Analytics and Cloud Services) at this level is permitted for all applications, both commercial and free, with no financial obligation to Appcelerator."

Again, APL code on Github. APL is a permissive and "biz friendly" license as we all know.

Appcelerator is open source for the sake of being considered open source. They certainly are not in business to promote businesses using their open source for free.

Yes, but how do you explain the contacting the developer (and the client)?
