Zoom has not committed any fraud. They clearly state that by default their meetings are encrypted, but not end to end encrypted. And that you can turn on end to end encryption, but that it causes a bunch of features to be disabled. I think this is a great balance between being able to add features that are impossible with E2EE, but allowing privacy concious users to choose if they need stronger encryption.
