They've been warned again and again about using the event as a political platform with attacks on republicans while praising anything the democrats are doing. It made the event boring and infuriating if you're a republican.
My guess is that viewership will decline so much that they'll have to take the broadcast away from NBC and shift the program over to on-line viewers via Peacock. They are sinking their own show for liberal politics. I truly don't get it.
