The channel name wasn’t changed, it’s still Fox News. They got in trouble for running opinion pieces in the middle of their news segments, and referring to some of their non-news people like Tucker Carlson as reporters and pieces they ran as news reports.

It was all tied in with the Dominion lawsuit and related cases around that time where a big chunk of their defense basically boiled down to “those things were said for entertainment purposes and were clearly exaggerations and hyperbole, no sane person would believe insert blatant but typical Fox News bullshit here”.

The plaintiff rightfully pointed out that if you present “opinions” alongside your so called news without clearly calling them out as opinions, many people (and pretty much every last regular Fox News viewer) will assume you’re making factual statements.

Among other things, as part of the settlement Fox News also needs to have fact checkers present during their news segments to call them on their bullshit which has led to some hilarious clips lately where the muppets pretending to be reporters get absolutely demolished by the fact checker in real time.
