There can be no 'request' without associated 'acceptance' of that requet.
Therefore we have two 'half-links' where the content provider thinks it
beneficial to pay for the other half-link in order to get its traffic
delivered to the content consumer paying the other half. A corporate website
covers its cost of the half-link in product sales while a more serious
content provider sells subscriptions.

A colo charges the website publisher not only for rack space etc. but also
to provide the half-link to content consumer. So the colo has the fees and
will pay if peering is asymmetric.
