My take on Murdoch’s firing Tucker Carlson: it was simply that he wasn’t profitable after all. He might have brought in $100m in ad revenue per year (not all of it profit) but at almost $800m in this settlement, and another lawsuit in the pipeline, his lifetime profit contribution for Fox may essentially be zero or even negative. So they get rid of him … and clearly communicate to the next guy that they better not do that stuff again. Stuff=endangering profit. Sufficient explanation imho.
