Maybe we should bring back the FCC fairness doctrine. https://en.wikipedia.org/wiki/FCC_fairness_doctrine
The UK has such a regulation still, for TV broadcasters only. It also has the BBC which is committed to such fairness and neutrality in its charter.
In practice it is not enforced. For example the senior management of Channel 4 news have routinely made tweets that indicate they hate the Conservative party. And I mean really hate.
Their head of output retweeted a message that said, "Writing from America & I can assure you that conservatives will absolutely keep needed medicine out of the hands of those who require it, if you let them"
One of their most famous and senior journalists (Jon Snow) went to a music festival, someone who partied with him claimed he shouted "fuck the Tories" and "I'm supposed to be neutral". He claims he can't remember if he said it or not.
The chief editor of C4 News liked a tweet that said simply, "Boris Johnson is a cunt". Johnson is one of the most well known conservative politicians in the UK and was a cabinet minister until he resigned quite recently over a policy dispute.
You can see a pattern - journalists who are supposed to be neutral by law have no problem with broadcasting to the whole world personal insults against conservative politicians on Twitter. They get away with it because the regulator stands by and does nothing.
The FCC fairness doctrine is unlikely to work out much differently. The USA is right to avoid it.
