I might be wrong here, since I only have this from hearsay, and I certainly won't touch Zoom. But, wasn't the "end-to-end encryption" a term they used in a blatantly deceptive way? The two ends not being the two users, but the user A and zoom servers, and zoom servers and user B? Please do correct me if I'm misinformed.

Edit: I checked. They've got you fooled.
