Great story; I don't buy it. I haven't purchased a commercial-grade router (for values of more than just 'Cisco' or 'Juniper') that couldn't support IPv6 (admittedly for better and worse levels of 'support') since the early 2000s. If Amazon wanted them, they would have been supplied. Maybe it's "no one can supply routers with the IPv6 support we want (snowflake emoji)" or "we can't deploy the routers fast enough operationally". But not enough v6 capable routers is a stretch.

And even so...this anecdote is/was 'many years after the fact', so what's the issue now? Easy: they don't need it enough to spend the money to operationalize it.
