It seems like they don't publish every day, but do publish regularly formatted json files so an Atom feed would be the "don't pay AWS to read about AWS" approach

e.g. https://aws-new-features.s3.us-east-1.amazonaws.com/update/2... and then https://aws-new-features.s3.us-east-1.amazonaws.com/update/2... is present but basically empty and https://aws-new-features.s3.us-east-1.amazonaws.com/update/2... is 403

also: https://aws-new-features.s3.us-east-1.amazonaws.com/html/aws... is the link found in the screenshot

I long for a SaaS company that questions complexity and simplifies offerings.

Imagine: "We've been questioning whether our customers actually needed all these slightly different services with such labyrinthine pricing plans that no one understands, so we decided to group a bunch of them into an all-you-can-eat plan that internally uses the same backend, instantly saving you money without you having to lift a finger."

Obviously, that's wishful thinking: It will never happen. SaaS companies only ever increase the complexity of their offerings and pricing plans over time.
