Im of the opinion that for commericial tv, there has to be some commentary from the commentators, but not too much. I think total silence would be unhelpful for many. If it were like a live stream e.g. JGP, all for silence. But for commercial tv, not so much.
I think that some effective commentary during a performance can enhance the viewership experience.
