I guess if we’re returning to a simpler age then all ads are display ads & rates are set by guesstimating website reach using old school methods: things like actually going out and surveying your target audience to see how many of them actually read the site in question.
If the new normal is “We've sold our customer’s privacy and personal data to the highest bidder and yet we’re still wasting 50% of our ad spend & have allowed a faceless Silicon Valley company to insert itself in between us and our customers.” then the old way of doing things suddenly looks quite attractive by comparison.
