Yes, but I disagree. I think it is actually better positioned than Facebook to build a big business. Twitter can advertise against breaking news, sports, celebs - a ton of eyeballs. And they don't have the obstacles around privacy and personal data that FB does. That being said, I think they are making a myopic decision by shutting out their third party clients. A ton of innovation has come from those developers and they could easily find ways to integrate them into their advertising plans.
