That’s not end-to-end encryption. By that logic HN, and any other website over HTTPS is E2E encrypted.

Is HTTPS really always E2EE?

I was under the impression that large companies work with proxies so they can do deep packet inspection.

PS: you are right of course.

That is what "end-to-end encryption" has come to mean in marketing. In the same way that every single product is "natural."
