I feel this is a blessing in most cases.
Remembering in-person meetings, half of the “participation” was asking to get back one slide before to check a point that went too fast, questions on points that are dealt with two slides further, people getting asked questions as a punishment for being visibly bored to death, and facts that could be checked by a 10s document search but would seem rude to be looking for right now.
Forcing people to share their documents, everyone free to get back and forth in the slides on their side, and just able to cut the camera/mic and look for whatever they feel they need to look for, do whatever they need to do just helps tremendously to cut down on unneeded back and forth, and improves a lot on efficiency.
