I guess I still don't understand how Appcelerator knew who the 'design agency' was for the end client. Was the app advertised as being built in Titanium by XYZ firm for ABC firm? To follow up on my original point: The OP makes it seem like Appcelerator is shaking them down after the fact (and breaking the licensing/pricing model advertised for the product) yet there is no evidence of it. No one at Appcelerator has confirmed this has happened nor has anyone else in the comments had a similar issue. It sounds more like Appcelerator reached out to upsell and it was taken/communicated badly.
