Advertisers need to fuck off. Ads are never going to work on the web - the ad bubble needs to pop already! Advertising on the web is a horrifying web of fraud, psuedoscience, and invasive tracking and sensitive data hoarding. Frankly, it should have been outlawed by now.
While everything that is going on with ads is horrible, it does work. This is very wrong side to hope for things get better. There is fraud but companies pay premium for ads because of it and in the end customers.
I agree, but it will be ugly. These "ad" companies are really surveillance companies who can currently print money by selling ads. When the bubble pops, they'll still have all of their surveillance data, but will be forced to sell it in different and sleazier ways. Think credit reporting that is technically not "credit reporting," job applicant screening based on web histories, reporting on political dissidents, etc. FB/GOOG will get seriously evil as they collapse.
