Yeah, but presumably mainly because it's just much cheaper for Amazon to make their own (technically inferior but it doesn't matter if you don't care about single-core perf) chips than having to pay for Intel/AMD's margins. Of course from the end-user perspective it doesn't matter. But long-term it might less lead to less competition allowing them hike up prices in the future. Of course other hyperscalers can and presumably are doing the same. However everyone else will be left out unless Ampere (or somebody else?) steps up.
