Steam is only DRM in respect to it only allows you to play what you've bought on your account. To try and draw a comparison between Steam's "Passive DRM" and an "Active DRM" product like Securom is silly and your post is quite frankly petty.
I completely disagree, there will -never- be such a thing as an anti-piracy tool to demotivate pirates. The more secure a system claims to be the more driven the crackers become.
Heck, I bet a great deal of the cracks out there are made by people that probably don't even play games.
STEAM is anything but passive. If you buy a game, I'll use CIV5 and FEAR3 as an example. You have to create a STEAM account to play, even if you bought the games at a store. Ok, one you are registered the automatic updates begin. I just want to put the cd in and play the game!!!!!! STEAM tells me when the game will be ready to play, funny, I was ready to play it when I bought it!
And for those who say "offline" mode, first you gave to sit through the gigs of updates before STEAM will let you play the game you bought from another store.
