Someone made modifications to our module without our consent. They removed our GitHub information and embedded the modified module in their Twitter application. As a result, the user interface of their app is redirected to activate all of our features, without giving us proper credit.
We strongly condemn this behavior. Thus, we have no choice but to close source and refuse to work on ANY modified Twitter client in the future.
