While much of the anger makes sense, why do folks keep harping on Google for using 3rd parties for their marketing? I know of no media or marketing company of any reasonable size that doesn't outsource some part of their marketing to another agency or marketing services company. Yes, even agencies outsource some of the work to promote themselves... to an agency. Should Google have more oversight into what they are paying for? Sure, just like everyone who hires a 3rd party to do stuff under their name and aegis. But just because Google have built the technology to run video ads, do we naturally believe that they also have the creative, marketing ops, and other pieces/talent/staff necessary to build, manage, measure, and improve the campaign? Perhaps, but from a resource and efficiency POV, they may find it cheaper to just outsource that to an agency and keep fewer resource in-house for marketing vs., say, engineering. It's ok for companies to purchase services from other companies. Not keeping a close eye on what you've bought, however, is another matter.
