Because watching them pays all the others. The evening opinion shows are what pays the bills. You watch....you put money in the pockets of the Murdochs.
The opinion shows are on contract, they get paid regardless of ratings until their contracts are up. FOX stabbed their fans and Trump in the back. There are some, like an abused spouse who don’t mind.
When I cancelled Fox and all the major news stations and tried on INFINITY to get just NEWSMAX I was told that package would include all the stations I wanted to get rid of.
I knew Fox,CNN,ABC,CBS etc. would get money from that package even if I didn't watch them , or had cdrtain channels blocked, so I cancelled the package , and get NEWSMAX free on my laptop computer and not on my TV. -Tom
