Innerfence recently launched an app named Infinite SMS which allowed you to send unlimited SMS for free. The service used a free service from Google currently in "Experimental" stages - according to Google. The app soon reached the Top 10 list on AppStore and that's where the trouble started.
According to Google, they had to cut them off because of the app's HUGE popularity; stating they were unable to cope with the expenses. And being an experimental service, Google was not willing to bear the extra costs, so BOOM - they blocked the developer.
The developer doesn’t have much to say but they have tried to express their grief in just a few short sentences.
