It would be nice if they came and asked us before they put a product out but Zoom lost $10 billion off their market cap over this flap. Good crypto people aren't cheap but Zoom can easily afford to fix this. I am sure there will be no shortage of top rank folk willing to join up to their technical board because this is a technical board which might actually meet (virtually) and do something for a change.

Security that demands anything of the user is not going to fly. The challenge is not to make a version of Zoom with all the usability of the PGP mode in vi. The E2E version has to be indistinguishable from the regular Zoom experience unless the user decides to ask how secure they really are.

Given the circumstances, the short term fix is going to have to be a proprietary one with limited functionality. But the long term goal should be an industry standard security protocol that provides E2E all the time unless there is a gateway to a non E2E system in use.

You are absolutely correct, but this current flap is being fueled
by players who desperately *want* Zoom to fail: Facebook, Google,
Microsoft, NSA, GHQ, etc., etc.
These players have already spent billions acquiring and/or hacking
existing systems; they don't want to have to keep investing more $$$.
The message is going out: startups, don't even think about coming
out with true end2end encryption, because we're going to crush you
They're also working behind the scenes with crypto killers like
EARN-IT to cast their desires into law. See the latest post by
Signal, that they will be forced out of the U.S. by EARN-IT.
