I think a lot of developers are looking at this in the wrong way. Twitter realizes its potential as a service. It has been used to topple governments in the last 5 years and to stage massive political movements. A lot has been changed thanks to Twitter's method of communication. In the past year they've hired multiple security experts and have begun making their product more secure (look at the patches to the Twitter client). I think their move to create licensed applications may not be as much for money as it is for security and having trusted sources. Lets face it, most applications you can't trust with your security. This allows Twitter to have a say in who meets their standards.
