For me, that quote about sums up the rest of the article. Too much arrogance in there for me.
While a bit slick/sleazy in their approach their work revolves around using social psychology principles (social proof, scarcity etc), conversion tricks, clever copy, giving away freebies in order to build up their email lists. These guys eventually upsell on their premium products for a ridiculous price whilst offering their digital product for a "limited time only" to convert users who've got a good amount of value from their give-away products.
There's hardly any regulation in this industry and the FTC has come down hard on these guys on more than one occasion.
I think we're all onto these guys and for him to think (or any other "internet marketer") they can take advantage of others through information asymmetry will be thwarted.
