It was a liberal hit job. Hollywood is part of the lunatic left. Ailes was right wing. Everyone knows that. If he abused his power then no one likes that.
On the other side of the coin CNN is also part of the 1%er media globalist families only they promote socialism and open border globalism. Globalists use the socialists as voting fodder and angry hate-filled activists. CNN has been accused of antisemitism and racism.
Matt Laurer was also fired for sexual harassment and abuse of power in the workplace at ABC. You likely will not see a Hollywood film about that. It doesn't fit the Hollywood political narrative that Hollywood likes to spin.
