Twitter discards client UI community

The announcement at http://groups.google.com/group/twitter-api-announce/browse_thread/thread/c82cd59c7a87216a?hl=en shows that they intend to switch from the "bazaar" model of development to the "cathedral", with much tighter control of user interfaces for "security" and "consistency".
