OK, then Disney+ or Hulu or whoever.  Peering wars never end well.  Don't 
even need postcards, just stick the flyer in with the bill.

AWS has perfectly good support for IPv6 so they must have business reasons 
to stick with v4.  But I expect the cost of putting up banners on the 
homepage saying to call your ISP, for people coming through the relevant 
ISP, would be pretty cheap, and Amazon's customers appear to like their 
accounts and their Prime quite a lot.  Again, peering wars never end well.

This ignores the question of what the advantage to the ISP would be other 
than bloody-mindedness.  The world is not going to abandon IPv4 any time 
soon and the last time I looked, the cost of routing packets is the same 
regardless of which header they have.
