Aws is an infrastructure company that builds services on top of that infra to sell more of it at a higher margin.

Anthropic trains models on AWS's (and GCPs, and Microslop's) infrastructure, then skims margin off of selling inference also on the infrastructure owned by the other companies.

These are extremely different businesses.

Anthropic's constant changing of its mind leads to instability which leads to unhappy customers

I’ve never gotten a refund from Athropic.
