It turns out that Zoom actually does encrypt "end point to end point" as they have stated. The initial Signal article was in error and the Reuters article is being misleading by omission by failing to mention that.

I think an encryption privacy consumer protection law would force a company to say how much work they would have to do to get access to the E2EEed data. As it is now, the expression "end to end encryption" is practically meaningless. The Zoom case is an excellent example.
