"Misinformation" is just a codeword for "things I don't like."
That's what the people with an ideological agenda tell us. They are wrong. Misinformation is a real thing, and it is damaging our society.
Some people call it "truth decay: the fact that people pushing an ideological agenda realize that lies are as powerful, and even more powerful, than truth in energizing the outrage that fuels their agenda. And social media in particular is full of half-truths and outright lies.
However, the government anointing some news sources more "trusted" than others is not a solution. The government, or some people in the government, also has agendas to push, and wants to devalue trust in truths that may damage that agenda. "Telling the truth to power" means telling things that those in power don't want to be told, and these are voices that we need to hear.
