In an announcement on Monday, Twitter introduced a new way of censoring COVID-19 vaccine “misinformation” on its platform. The social media giant plans to attach labels to tweets that have “misleading” information about vaccines and will link vetted public health information instead. The new “strike” system will include labels that appear as pop-up messages in the retweet window. In a similar move, Facebook introduced a new policy that will aim to censor the COVID-19 virus and vaccine “misinformation”; however, some users have argued that the censorship blocks their freedom of speech. The tech giants have faced severe criticism in recent months over their censorship strategies, particularly after banning former US President Donald Trump in the wake of Capitol riots.
