I can't understand the reasoning here.

They need to go after other service provider, not isp. ISP provide CGNAT to facilitate access to ipv4 only service.

Yeah I don't have much any problem with doing CGNat. We need to get the ISPs to do IPv6, and we need to penalize AWS when a customer chooses to do IPv4 only. (They will pass on the fee, which is just fine easier than going after the customers directly.)
