This Twitter client situation reminded me of some ancient (1999) history, so in case you're wondering how far companies will go to try to enforce a theoretically-impossible preference for one client of their service... The MSN Messenger team added America Online chat support to the Messenger client. AOL didn't like that and tried a variety of approaches to reject Messenger. The protocol was undocumented, so there were lots of tricks they could play. At one point they went (IMHO) a bit too far: they deliberately exploited a buffer overflow in their own client!
