WorkOS
The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.
The author needs to ask themselves: in this cloud technology stack, is there POSIX involved somewhere lower down, where I can't access it? The answer is, of course, "yes". The sort of cloud storage systems described all run on top of POSIX APIs. They provide convenience (cost efficiency is more debatable) compared to the POSIX alternative, but that's because they exist at an entirely different conceptual layer (hence the presence of POSIX anyway, just buried).
Your point about surfacing a POSIX that's actually there but hidden and thus visible to low-level Amazon employees building the S3 service which makes it invisible to S3 end customers is true but isn't the the point of the article. The author is saying there are motivations for a POSIX-like api visible also the end user.
So your explanation of stack looks like 2 layers: POSIX api <-- AWS S3 built on top of that
Author's essay is actually talking about 3 layers: POSIX <-- AWS S3 <-- POSIX
That's why the blog post has the following links to POSIX-on-top-of-S3-objects :

POSIX and web are not incompatible thanks to emscripten and the use of musl. I am creating à UNIX like operating system running in a web browser https://www.exaequos.com
