Nobody except the 140M subscribers on T-Mobile US's network:

But sure, be IPv4-only and add latency by forcing traffic through an extra translation box.

It's because big tech is USA based mostly, where there's still a glut of ipv4 available.

Definitely not for the biggest ones. Google and Meta have so many machines in their data centers that IPv6 addressing becomes a technical necessity due to the risk of exhausting the RFC 1918 address space. Naturally, they were early adopters of IPv6.

Well it’s over 50%…
