Why has Cochrane been 'shadow banned' from Instagram?

The COVID-19 pandemic has not done social media platforms massive favours in terms of demonstrating their commitment to banning misinformation.

Instagram — which is owned by Facebook — has been criticised for providing a platform for people like US antivaxxer Sherri Tenpenny, author of Saying No to Vaccines.

Perhaps it sees it as an issue of free speech. But then it has taken steps to weed out other forms of misinformation by banning any mention of Cochrane.
