This week, YouTube silenced yet another medical expert with a dissenting opinion on Covid-19 response, in accordance with the platform’s new terms of service that block anything that challenges W.H.O. recommendations. Prior to censoring Dr. Wittkowski, the platform removed the following videos from Drs. Erickson and Massihi.

Here are 12 more experts who’ve expressed dissenting opinions. By definition, a novel virus is going to have some surprises for “the experts,” and the free flow of information is critical to solving the problem. For example, last month Dr. Cameron Kyle challenged the accepted orthodoxy on ventilator protocols for Covid-19, potentially saving many lives.
