That still doesn't make it a Trojan
The Game belongs to Valve, it is their game.
Again "Steam's development began at an uncertain date prior to 2002. Working titles included "Grid" and "Gazelle".It was revealed to the public on March 22, 2002 at the http://en.wikipedia.org/wiki/Game_Developers_Conference, and was presented purely as a distribution network."
Just stop, i understand if you don't like Steamworks or DRM, just don't go making outlandish claims about software that are not true.
