They only show logos on mail that's DMARC aligned, but that just tells us 
that the domain on the From: header really sent the message.

They're trying to invent third party validation services to attest that 
logos A, B, and C can be used by domains X, Y, and Z, and then explain 
why that will work better than EV certificates.
