Twitter updated its Developer Agreement, effectively prohibiting the use of third-party clients. Platforms like Twitterriffic and Fenix, which were shut out earlier this week and no longer have API access, are now essentially useless.
It is forbidden to “create or attempt to create a substitute or similar service or product to the Twitter Applications,” according to the new regulations. Simply put, the platforms of such apps’ developers have been “suspended.” Currently, tweets can only be embedded using the Twitter API to integrate Twitter Content. However, developers are no longer permitted to alter any of the visual components or how the information appears to the reader.
Another factor limiting the ability to monetize users using these clients is the fact that Twitter does not serve ads through its API.
