There is a convention to the use of the E2EE term. All encryption involves a party that encrypts and one that decrypts. When the German U-boat operator used an Enigma machine to decode a message off the radio no one then or now would call what had happened E2EE. That is even in the face of the fact that many operators in many U-boats were decoding the same message. EteSync works in the same way. E2EE is a term normally only used when some distinction from a default case is important. It is in a sense a weaker term than just "encryption". It is normally only used for particular cases in messaging. Something like: "All data is strongly encrypted at all times when off the users devices." strikes me as stronger, better and easier to understand in this case.
