Likewise to it being off at our house too. We are down to Fox Business, watching Varney in the morning and checking Dobbs in the PM a couple of times a week.
What drove us away was the inane comments from the libs that would never shut up and like you said, always go unchallenged. I think this was part of the idea behind creating the Fox Nation thing that people (not me) can pay for. That may be making them some money while allowing them to move the cable broadcast to the left. I don't follow ratings, but I'm guessing Fox is slip sliding away.
Looks like I am not alone. Still watch fox and friends. Rarely turn on Fox for anything else.
