When my client updated recently there was a new license agreement to subscribe to. I'm not a fan of skipping through these because there's always some manner in which you have to tie your hands behind your back and willingly gag yourself if you're not happy with the game or service you're subscribing to. And while I've never seen Valve as a company eager to look out for its own interests first (its always professed to be about making games for gamers to enjoy), the new agreement shows that for some reason the company is trying to protect itself.
