I don’t think they were stupid enough to use zoom.
They had 4 years to plan this.
Actually, they were.
Because of COVID and mail-in ballots, they thought they had the steal in the bag. But Trump's vote totals far exceeded what they had, it completely overwhelmed them. So it was either manufacture more votes or pause the count.
I believe the Zoom (or a similar conference call) was done early in the night around 8:00 PM when it was clear Trump was kicking rear. Pausing the vote count has never happened before in U.S. elections.
Hillary’s aide Huma Abedin was dumb enough to use Yahoo mail to forward classified state department docs.
