"P&G To Online Ad World: We've Had Enough" - https://adcontrarian.blogspot.com/2017/01/p-to-online-ad-wor...
Digital advertising is rife with (what should be considered) fraud. Advertisers feel as though they are getting fleeced, and the advertising middlemen reap massive margins. The accountability isn't where it needs to be; there are websites that hide ads under other ads, still reporting displays for all ads per page load. I suspect moves like this one will help the ecosystem change for the better.
