In addition to the other posts, Valve has built up a solid amount of good will with the gaming crowd. They might not have the best support, but their actions up until this point suggest they take gaming seriously and just don't see all their users as a revenue stream, like you see with EA and Microsoft. They aren't beholden to shareholders so as long as guys like Gabe are around, people are less worried that Valve will start fucking with customers in the way you see other companies do.
