AWS Announces AWS Wickr (opens in new tab)

From the Product Page [0]: "AWS Wickr encrypts every message, call, and file with a proprietary, 256-bit end-to-end encryption (E2EE) protocol. No one but intended recipients can decrypt them, reducing the risk of person-in-the-middle (PitM) attacks."

Why do we need proprietary protocols for this?!

I wasn't able to readily find a "show it to me," but the Enterprise page has a vimeo so I'd guess it's similar enough to the non-Entetprise versions: https://wickr.com/wickr-how-to-enterprise-end-user-features/

The Pro page <https://wickr.com/pro/> has a comparison PDF showing how it stacks up against Signal, Slack, WhatsApp, etc https://wickr.com/wp-content/uploads/2021/01/Wickr-Pro-1.pdf

"Now even AWS can decrypt your data."

Even if AWS is served a warrant? Excuse me if I choose to wait and see on this one, especially when there are better zero-knowledge solutions (like wire.com) out there.
