I find myself doing exactly this myself, if only to anger my ISP (Shaw Communications), who likes to throttle bittorrent connections. I also force my apt-get dist-upgrade and emerge -eaUDv world downloads exclusively over Tor and I2P throughout my enterprise for the same reason. I'm positive I set off red flags and waste precious resources to monitor my download habits, hopefully diverting attention from others that need that anonymity and privacy more than I do.
