I was a bit surprised by this statement: "it’s pretty obvious that throttling all traffic based on application type definitely violates the principles of net neutrality". Setting aside the specifics of what T-Mobile is doing in thsi case, I thought the 'neutrality' in net neutrality was about neutrality of content provider, not content type. If I throttle all bittorrent or video traffic equally, it might be annoying to my users but I don't see why it is not neutral.
