It is an indicator of the times.
So many people want to purchase a solution or a result, the vast majority of the population can not cope with uncertanty unless that uncertanty provides promises of significant gain.
So instead of using the two most important things at an anglers disposal.."observation" and "thaught", they want to buy product, services or information to guarantee a result.
Even more so they mostly expect it cheap.
