I had an opportunity to engage with the industry and the marketplace in many ways prior to GDPR. For example, in 2015, when Apple enabled ad blocking in iOS, that created a considerable discussion in the publishing industry around the effects of this, so I engaged with industry at that time.
What's interesting in looking back on that debate is that it was whether ads were annoying or it was privacy anxiety. I was trying to argue that it was privacy anxiety, and they didn't want to believe me.
Now, after Cambridge Analytica and GDPR, you can make the case that privacy anxiety is a driver in the ad blocking question; therefore, how does it fit into GDPR consent interfaces that explain the business to consumers so they can understand how monetizing works? To me, it's the idea that GDPR was a kind of teachable moment for consumers and the industry, to say that this is how this industry works.
The problem is that the research shows that the more people understand how digital advertising works, the less they like it.
