That's all fine but not responsive to my point. GP post said "but what if whatsapp silently hamstrings e2e overnight" -- my point is: what if my XMPP client/server does?
EDIT: I previously said "turns off E2E", which I didn't say in my original referred-to post, and that's more misleading than "hamstrings", which is how the actual attack works.
