It's not good to keep spreading false information...the people on the internet that don't know better will eat it up (No offense, I love everybody)
This is not false information. It has been confirmed SC2 uses TCP. You are right about the majority of games using UDP, but SC2 is an exception, and uses a point-to-point TCP connection.
Just a note on the TCP / UDP issue, this has already been confirmed by a TL admin some time ago.
