It mentions "DRM - STEAM".
As far as your other comments:
1) I've been using Steam for a while now and it never crashed my computer. It downloads at about 2.4/mb and I can do something else in this time, even something like playing a game.
2) Almost all publishers are using a DRM or another - Steam is the lesser evil of them all. Comparing it to UbiSoft or Origin, Steam is actually non-instrusive.
3) It's not a rip-off. You've bought $100+ worth of games for $20.
The only down-side of Steam is that yes, you can't (I think) play while offline. When Steam was launched with Half Life 2, it required only a one time connection to activate. Now I'm almost sure that you must be online all the time.
