FYI, that is called paid peering.

But, it does not mean both parties of the peer are equally
benefited. As such peering may be paid one, though it
may not be the current practice.

Given the observed profitability of CDN providers, CDN
providers are, seemingly, more benefited (because they
are not neutral), in which case, CDN providers should
pay to access/retail ISPs.
