I don't think it mentions anything about Twitpic as a service. It's only about the trademark. That being said it makes a lot of sense for Twitter want to control the user experience. The cost of hosting low resolution thumbnails can't be a pressing issue for Twitter. User experience and engagement on the other hand.... I'm not saying it's worth sabotaging relationships with 3rd party developers but there's a certain mindset in which this type of thinking makes a lot of sense.
