Big Tech companies are aggressively tamping down on COVID-19 misinformation" - opinions and ideas contrary to official pronouncements. Dr. Knut M. Wittkowski, former head of biostatistics, epidemiology and research design at Rockefeller University, says YouTube removed a video of him talking about the virus that had racked up more than 1.3 million views. Wittkowski, 65, is a ferocious critic of the nation's current steps to fight the coronavirus. He has derided social distancing, saying it only prolongs the virus' existence, and has attacked the current lockdown as mostly unnecessary. Wittkowski, who holds two doctorates in computer science and medical biometry, believes the coronavirus should be allowed to create "herd immunity," and that short of a vaccine, the pandemic will only end after it has sufficiently spread through the population. "I was just explaining what we had," Wittkowski told The Post of the video, saying he had no idea why it was removed. "They don't tell you. They just say it violates our community standards. There's no explanation for what those standards are or what standards it violated." In articles and interviews across the web, he has likened COVID-19 to a "bad flu." That likely made him a target for YouTube. "Anything that goes against [World Health Organization] recommendations would be a violation of our policy," CEO Susan Wojcicki told CNN.
