Except 100,000 is not a lot of user tokens. In fact in the iOS world (where apps often cost $0.99) you could easily be failing if you only have 100,000 users.

And you don't mention the 200% cap on new users. That's not "many third-party Twitter clients have dedicated user communities and passionate developers, and with focus on keeping in step with our evolution, they should continue to thrive with their audiences." That's more like "third-party clients should stop developing, like now. There is no future for you with twitter".
