FB represents a hugely powerful new ally that helped Dems against Trump. They had always wanted to reign in Big Tech in the past, but Big Social media is a different animal and alliances change.
2. the SCOTUS is quite clear about this activity that the Biden WH is engaged in - it violates the first Amendment including when they direct the censorship though a private business proxy. And it's really obviously a horribly bad idea just waiting to bite you guys in the ass when the pendulum swings back the other way.
Rationalizing how much good you think it does doesn't change the illegality of the action. Arguing that "Top organizations" are overseeing it doesn't change that fact either (and we have all seen how these organizations have been politicized). Also, those "top organization people" at the CDC just screwed up by censoring true stories about the coronavirus origins in the Wuhan lab in China. They have proven they offer no assurances when it comes to censorship oversight.
The government should no tbe involved in censorship of it's own private citizens. Period.
