GoDaddy is being sued because that's where the money is. Class action lawyers (and many other lawyers) are not trying to make the world a better place, they are trying to cash out.
That goes without saying, at least from the lawyers' perspective. I think it's possible that the victims are also just lashing out because the site would not exist if hosting providers refused to host it.
This is all to true in a lot of cases. I regret there aren't more organizations like the Center for Class Action Fairness who object to ridiculous terms where lawyers just "cash out", often leaving the class with very little.
