I believe this is true of multiple content networks.  For example, we
peer with Amazon in a couple of locations, but a significant amount of
traffic frmo their AS comes across transit rather than peering.

In old terms, this is "hot potato" routing - where the source gets the
traffic out of their network as soon as possible, rather than spend
internal resources to carry it as close to the destination as they can.
