This is the best summary I could come up with:
Carriers and Big Tech are happily continuing to use network address translation (NAT) and IPv4 to protect their investments, with the result that transition to IPv6 is glacial while the entire internet is shaped in the image of incumbent players.
That’s the opinion of Geoff Huston, chief scientist at regional internet registry the Asia Pacific Network Information Centre (APNIC).
He argues the widespread use of NAT masks the fact that the internet is largely stuck on IPv4 because incumbents don’t see the need to change.
"The widespread use of NATs in IPv4 limits the technical substrate of the internet to a very restricted model of simple client/server interactions using TCP and UDP.
“Today’s internet carriage service is provided by a smaller number of very large players, each of whom appears to be assuming a very strong position within their respective markets,” Huston observes.
APNIC expressed similar concerns in December 2021, when a report jointly commissioned by Latin American internet registry LATNIC suggested that big tech’s in-house networks carry a huge slice of global traffic, giving the likes of Google and Facebook enormous influence over internet architecture.

There is a reason for this. While ipv6 has essentially unlimited addresses, it is a pain in the fucking ass to deal with and in many ways causes more problems than it solves.
