I've been in many meeting rooms where there's a single projector/tv, and the person controlling it only shows either the remote cameras OR their screen (while they're sharing), so that isolates the remote people even more. (I've also been the remote person in this situation, and it definitely feels more like being an occasionally noisy fly on the wall then a full participant).
Everyone also gets their full desktop (big/multiple monitors, full keyboard, etc).
It'll be interesting to see what happens post-lockdown.. will the people miss the benefits of "one remote = all remote" and have more empathy for remote people, or will we go back to the same old?
