That makes sense for the zoom sessions. But, although I've never run a conference, I naively can't see that broadcasting the plenary session's video a little broader (to the three to five latecomers likely to stick around!) would really cause problems. Not to be a stereotypical "Concerned Facebook Taxpayer", but in general I'm really fond of CERN's transparency, and I appreciate all the work they do to keep science open. They're usually way ahead of the field and it's refreshing to see, I love following what comes out of the LHC data. So all that to say, maybe I've set my expectations a little high when it comes to physics and public access =)
