I feel End-to-end is over marketed. Yes it protects your data from transmission pipes, but data on both your "ends" can be easily controlled and duplicated. Your picture on your device can be accessed by 3rd party, so does your data on the server.

Not in my experience, except by very few

Some, still few enough to not make the term confusing, for what I can tell
End-to-end encryption is not a term used for communication between clients and servers, although I saw several marketers trying to do it.
For normal people E2EE means privacy, and that's why some company tries to sneak the term in products where it makes no sense.
