>E2EE is a term about encryption where no data between two devices can be read by eavesdroppers. That would cover any use of encryption. E2EE is a term used where there is a distinction to be made between access by users at the ends of the system and some other part of the system. Originally used to cover the encrypted email case where there is a lot of "middle" in the form of email servers and a small amount of "end". The term is often used incorrectly these days for marketing purposes. TLS could be used in an E2EE system, but it is normally not.
