Late last year, Facebook-parent Meta quietly phased out certain content labels on its platforms that for much of the pandemic had directed viewers to its central Covid-19 information page, after internal research concluded the labels may be ineffective at changing attitudes or stopping the spread of misinformation, according to a report Thursday by the company’s external oversight board.

Facebook also modified it’s search function to display government approved web sites first.

This was part of their efforts against “misinformation”, which has become a catch-all label for anything you have a different perspective about.
