Did they maybe translate it so they could link it to their citizens?

I really see no problem with this, they should provide the source code, but from what you said their modifications really aren't that sought after are they?

Don't open-source something if you don't want someone to clone it. What did you think was going to happen?

I don't see why someone would post the source to an entire app then watch the app store for a clone waiting to complain about it...
