That's what I thought too based on all the press (TC, RRW, Mashable), but the next day Twitter clarified that sites like Ad.ly and SponsoredTweets aren't in violation. Their change was aimed at services that show the Twitter stream intermixed with ads based on the content that aren't from Twitter. Since Twitter is rolling out their whole "in stream ads" platform that app developers can use soon, this seems to target that - and other places that try to target ads based on the surrounding Tweets. (note: I work on SponsoredTweets, so we've obviously been watching this closely. :)
