The more I think about this topic, the more I come to the conclusion there is one simple solution to all the targeted-ad related problems - at least from the platforms point of view: Make all data about ads public. Who is targeted, how many people are reached, what other campaigns does a company run on that platform. Let anyone see all the data and then don't blame the platform but the advertiser. Of course this would only work if at least the big ones (Google and Facebook) are be on board. Regulations which force all platforms to publish this data could minimize the competitive disadvantage that would otherwise result from companies wanting to keep this stuff secret and selecting platforms accordingly.
