Censorship by big tech at the behest of the U.S. government?
It was deeply disturbing to me that throughout the COVID epidemic many highly credentialed doctors and researchers were getting de-platformed for anything that remotely questioned the government's position on anything related to COVID.<p>Science is about asking questions, testing hypotheses and independent research corroboration.  There have to be checks and balances.<p>I expect the chilling effect from this experience will remain in the scientific community for a long time.
