Why do people think E2R encryption means the data can't be decrypted?
Probably a gross misunderstanding of encryption in general.

ANYONE with access to the keys can unlock it.
The ones with access to the keys own the platform.
The one who own the platform are legally required to submit your info to Subpoena, Homeland Security warrants, and Patriot Act related actions.

This is totally incorrect.

With end-to-end encryption, the platform doesn't have the keys. The clients exchange keys through the platform, but it's done in a way that the platform doesn't know what they are. A subpoena doesn't let them provide information they don't have. The platform may have metadata about your message, but not the contents.

On the Wikipedia page for Diffie-Hellman key exchange there's a good diagram explaining the concept of how you can exchange private keys through public transport. It's the one down the page a bit where they use paint colors. In the real world, it's done with math, but the paint concept is sound to understand the underlying idea.
