Personally, I think the likes of Capcom et al are not worried about 'lawmakers' so much, but are scared as hell of public backlash, esp from the likes of social media. They don't want the WalMarts of the world to get spooked and quit stocking their product.

A load of Maude Flanders-es shreking 'think of the children' on FB and a corp stockist being reminded by the Big Boss 'we're a family company and this looks baaaad' are immune to legal arguments, technical details or simple common sense. There are times you need to be seen to be doing something, even if it's utterly ineffective.
