I'm planning on boycotting every corporate sponsor of SOPA if it passes. Will there be any games/game companies left I can patronize?

Looking at this list of SOPA's sponsors, it appears as if I'll have to virtually become an ascetic to do it. But as an avid gamer I'm particularly interested in which gaming companies I can still give my money to. At a glance, it looks like most of the traditional "good guys" (Blizzard, Valve) are not on the list, and the traditional douchenozzles (EA, Sony) that I'd do well to boycott anyway are.

But am I missing anything? Any names on there that represent a larger umbrella for companies I like? In particular, I'm not sure how to respond to the ESA being on the list.

Just trying to plan ahead. Promising myself that I'll do this is the only thing that keeps the prospect of SOPA passing from literally turning my stomach.
