What do you mean? Obviously, as TFA shows and as others here pointed-out, AWS relies globally on services that are fully-dependent on us-east-1, so they aren't fully multi-region.
The claim was that that they're total hypocrites aren't multi region at all. That's totally false, the amount of redundancy in aws is staggering. But there are foundational parts which, I guess, have been too difficult to do that for (or perhaps they are redundant but the redundancy failed in this case? I dunno)
