I dont think theres any need to panic here... the FTC is doing this to force the Advertisers to properly disclose rebill info, which they should be doing anyway. From what I've read a lot of these guys were being incredibly shady, not sending anything after somebody paid cash, not offering refunds, etc. If you're going to pull that crap you deserve it IMO.
Nobody can ever take away an Advertiser's right to promote "get rich quick" concepts as long as theyre being truthful. Which is the real problem.
