All of those people writing those things advertise Twitter. As we all know Twitter has a huge drop off rate where people post a few tweets and then go away... forever. So Twitter is always in the need of new users. Let's say they do an Apple and kick out all of the various different add-ons that they make (while allowing ones that they don't make until they make one themselves). Eventually Twitter will just be another memory because the critical mass, people advertising twitter, will fall away.
