I image the logistics of the church building and the live stream camera matter. But I wonder if it also has to do with the number of people who are legally allowed to gather.
At my parish we have the priest, a sacristan, a reader, a cantor, and an accompanist. They all receive. I do not know if we have a camera operator. I suspect we do but that person may be able to operate the camera remotely so as not to be in the nave.
