Wasn't there for this, and am just catching up, but this is never OK. We can do better.
An adjacent point -- I have long complained about events wanting to review my slides weeks or days before an event. "Why can't I just bring it on a USB day of?" and often, they'll let me do just that. This incident is a reminder of why that's an unfair ask on my part.
I'm going to work harder to get slides in on time. Conferences deserve deck reviews before they show up on a giant screen.
(p.s. I don't know the situation with Barry's deck)
