Marketing hope to the hopeless, and the easy answer and magical panacea to the terminally stupid and lazy is a sure way to rake in the money. I'm not even sure if I think it's wrong to do so - most people in the Western world, or at least first world countries, have access to the internet. If someone is that stupid, then they've either got legitimate issues with their IQ and I guess are to be pitied, or they're lazy morons and deserve all they get.
