I'm already boycotting Sony over other things, so I can't very well say I'm boycotting them over this.

Walmart, too.

EA, too. (Stupid intrusive DRM. I'm missing a lot of potentially good games here!)

Nintendo? Ouch. That one's going to be painful... Oh wait. No, I only buy like 1 game a year from them anyhow.

Warner Music might be tough... I don't buy much US-based music any more, though.

And the rest I never use anyhow.

So the answer the question? People are either already boycotting them, avoiding them as much as they can, or just don't buy their stuff anyhow. At least, those people who would boycott over ethical concerns, anyhow. Those who don't boycott, they don't boycott anyhow!
