Muh dude. That ratings chasing is exactly why Fox lied to you.
the CEO, Sussane Scott, in an email dated December 2, 2020, to on-air corespondents said, and I quote "that the fact-checking has to stop now.”
Hosts Tucker Carlson, Laura Ingraham and Sean Hannity promoted the voting conspiracy theories, even though the hosts didn't believe any of it. We know this because of the emails and text messages they were sending.
They started off fact-checking then the CEO said it had to stop because they were losing viewers.
Fox lied to you for exactly the reason you think they didn't- they wanted to keep their ratings up.
