If I worked for Valve I wouldn't patch this game either. They released ONE patch for 1.6 not all that long ago... they were met with a constant stream of ***** and moaning from the general community as it changed the mechanics of gameplay and they demanded it be changed back...
I remember one CS:S patch when they fixed the head-height bug (which was partitioned by a previous Op here), they also added the new radar... The head height bug was fixed, but there was nothing but whinging about the radar as it made the game more 'noob-friendly' - all those people that spent the last 400 hours of their day-lives perfecting their 1337ness didnt like that at all!
If the community doesn't like it when the games are patched (in any way shape or form), then they can't complain when they don't come about!
