It depends on what type of meeting

It is definitely an issue that either you are actually looking at the other person, or they think you are looking at them.

There is no real eye contact on a Zoom meeting.

I can understand why people would want their cameras on. Communication with eye contact is helpful as you can see if people are absorbing what you are saying or not.

Being on a Zoom meeting with cameras on feels like being in an unfocused staring contest with a whole crowd of people at once.

I think people should try to put their cameras on if possible, but shouldn't be forced to.

Some say that they should be so that people can see each other like they do in person, and so that the person leading the meeting can confirm that everyone is actually there. Others say that it isn't like a normal in-person meeting because people don't bring their houses (or children and pets) to their in-person meetings, and also, at a regular meeting, people see each other from a much bigger distance than is between a person and a webcam.
