My guess is that he's assuming that uTorrent switched to UDP largely for non-technical reasons, essentially out of spite. Under this assumption it is quite natural to further assume that they are not going to use TCP-compatible congestion control, but something more aggressive. However the article reads like one big speculation, so I wouldn't read too much into it until technical details surface. Especially considering that ISPs can simply shut down all P2P UDP traffic and then install DPI filters and whitelist individual protocols as needed. That's if BT/UDP starts disrupting the 'balance of the Internet'.
