Even without these leaks if you add up the lack of communication, only impacting the top 25-50 Twitter API clients and clients showing up as suspended in the dev. dashboard. The only conclusion at this point is that it was intentional and not any kind of bug.
For the record, still no official or even unofficial communication from anyone within Twitter.
