I'm only partially convinced. I just can't see how you could really know if a company is using a hidden metric (or some sort of proxy for that metric so that they are not technically in violation) for figuring out what to promote. Short of having constants audits, how would you ever really know?

But my skepticism may be unfounded. Do you have examples of companies that are currently working with regulators to allow full auditing of their content promotion policies? Are they actually auditing these partnerships or are they simply accepting promises from the companies?
