Can anybody speak to why some of these "deceptive claims" settlements end up as a settlement with the FTC, which collects and disperses the funds in the form of refunds, while others end up as a class action settlement, where some private party sues on behalf of a class? In a standard class action lawsuit, the lawyers for the plaintiff (if successful) get a pretty nice cut of the settlement, and the remainder is dispersed to class members. But if the settlement is with the FTC, does it get its own cut, or does the entire settlement amount go out to class members?
