I don't think that was the claim. The question is rather, why do you need 25+ people for these tasks? They don't add new types of tweets every week/month and much of the interface (luckily) hasn't changed in a while. But I'd guess that these 25+ people spend only a fraction of their time programming and the rest with stakeholder management and corporate politics.
