Access/retail ISPs have no problem by peering with neutral backbone providers.
Neutral backbone providers don't peer with access/retail ISPs. They sell transit to them.
FYI, that is called paid peering.
CDN provided backbone only reduces costs of other backbone providers without reducing costs of access/retail ISPs.
Access/retail ISPs that peer with CDNs eliminate the cost of paying for transit for the content delivered by the CDN. That's what the initials CDN stand for.
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.
