Let's not overlook Agari, which has a financial stake in offering a 
solution to the problem they helped create. Notice how many dmarc domains 
direct the reports to agari, from which, for a fee, they will get nice 
reports and metrics for their CIO to show around, reports that will show 
how many times their domain was "faked". Agari has an interest in making 
those numbers big, and mailing lists help them do it. The Agari web page 
boasts how many users they "protect", and it features the kind of slick 
writing that impresses people who don't know nuts and bolts.

One of the great failings on Yahoo's part was introducing a Change without 
notice to those affected, not even their own customers (to my knowledge). 
Even sloppy business owners should know not to do that.

Agari introduced "Agari PRO" April 1. Dmarc was pulled from standards track 
April 2. Yahoo implemented dmarc April 4. What was the rush?

So true. In 100 years who will know the difference.
