There was already a forum post about this, so I'm just pasting in my previous response:
Yeah, I find it extremely odd how no one seems to remember how Steam was back when it began. And, if I remember correctly, many people were having similar knee-jerk reactions to it, declaring it spyware (which many people still do), dirty DRM, etc. (By the way, have any of you actually tried to see what Origin "takes" from your computer? These guys did.)
Whether or not people like it, EA has seen the writing on the wall. They know that physical retail won't be around for much longer, and decided that they want to be the first of the big publishers to get into the digital market, with the PC side being their test area. Over the course of the next couple of years (or perhaps even by the end of this one), they'll move their digital distribution to different platforms, with the eventual goal of drastically reducing or even eliminating physical sales of their games.
They also are aware that these first few years are not going to be pretty. Gamers, as they have shown in the past, are crazy averse to any changes in their hobby; a fact, of which, EA has been made aware of more times than you can count. They're betting that, like Steam, it will slowly ease into a space within the digital market that makes the service profitable, once the doomsday naysayers stop believing that EA is out to get them.
EA is only the first. Within the decade, I envision at least 2-3 other big-name publishers releasing their own digital distribution systems, as well as removing any and all support from Steam. It was fun while it lasted, but Valve won't always have the monopoly on the digital market. There will be legitimate competitors who will attempt to take a slice of that delicious digital pie that Gabe has enjoyed all on his own.
