Industry growth. Turns out it's a lot easier to "think of the children" when the industry is small and niche than it is when it's making investors billions of dollars a year. Turns out capitalism makes problems harder to solve once the problem itself makes money (see also: tax preparation)

That's also why the moral panic people switched from trying to censor games through government to trying to do it via finance (e.g. Collective Shout lobbying banks, credit cards, and payment processors).

Though if your question is about why the contrast between moral panic over game content and the lack of moral panic over actual victimization — I think that's always been the case, unfortunately. People seem more fearful of their children losing their morals than they are of people with no morals harming their children.
