It’s not an ignorant question. It’s a totally understandable question to have. This isn’t the first time they’ve done something like this in solidarity with other networks. Though there’s no one at the top of Fox making official statements I believe, the majority of people familiar with the topic seem to think Fox knows it won’t be only Rs running things forever and are trying to toe the line so they don’t get booted completely the next time a D is back in office. I don’t know if I really believe that because it’s not like Fox viewers would watch something else with better coverage, but it’s the most plausible explanation that I’ve seen posed.
