This is an interesting inclusion, would they be referring to copies of this book being sold on Amazon? Or usage in their documentation? I'm genuinely curious what the issue is with them...

Not sure but I assume it's Amazon offering Postgres as a service through AWS Aurora.

Unlikely, Postgres license is as liberal as they get:

Many providers offer postgres as a service.
