It’s also about “controlling” the image.
Wasn’t always like that. And if you are “good enough”, the artists (maybe not their management but the performers) can be appreciative (as long as it isn’t intrusive).
Youtube videos often look like crap and sound like mud though. The cameras have too much shake and don’t give a “good” impression what a performance was like.
