This is why people need to think for themselves. The article provides a link to the courts decision. Fox's position is described in the decision. Here it is, verbatim:
"Fox News again moved to dismiss. The motion argues that when read in context, Mr. Carlson’s statements “cannot reasonably be interpreted as facts” "
and again,
"Fox News seeks dismissal at the pleading stage on two constitutional grounds. First, it asserts that Mr. Carlson’s statements on the December 10, 2018, episode of his show are constitutionally protected opinion commentary on matters of public importance and are not reasonably understood as being factual. "
and here:
"Fox News first argues that, viewed in context, Mr. Carlson cannot be understood to have been stating facts, but instead that he was delivering an opinion using hyperbole for effect."
and the court then rules:
"As a result, the Court concludes that Mr. Carlson’s statements viewed in context are not factual representations and, therefore, cannot give rise to a claim for defamation."
and finally,
"Plaintiff Karen McDougal claims to have been defamed by accusations of “extortion” leveled at her by Tucker Carlson on Defendant Fox News Network’s broadcast. However, as described herein, Ms. McDougal has not offered a plausible interpretation that the statements Mr. Carlson made, when read in context, are statements of fact. The Court concludes that the statements are rhetorical hyperbole and opinion commentary intended to frame a political debate, and, as such, are not actionable as defamation "
