On account of stuff he said that is mostly correct and even obvious but exposes the cult of the science expert:
MANY MEASURES, John Ioannidis is a lion of medical science. The Stanford University professor is the author of some of the most cited journal articles in medical history. His research in statistics and biomedicine has arguably changed the practice of medicine. A 2010 article in The Atlantic said “Ioannidis may be one of the most influential scientists alive.” And you would never know any of this from reading comments about him today.
It started on March 17, when Ioannidis published an opinion essay in STAT saying that the data on Covid-19 were not sufficient to know the disease’s true prevalence and fatality rate. He also argued that scientists were in the dark with respect to which distancing and lockdown measures work, which don’t, and what the measures’ downstream harms might be. All of which was true — even if his very early estimate that as few as 10,000 might die in the U.S. turned out to be wrong. Ioannidis went on to say that preventing people from working or leaving their homes could cause more harm than the virus itself.
It was this last bit that set off the firestorm of criticism.Jeanne Lenzer and Shannon Brownlee, “Opinion: John Ioannidis and Medical Tribalism in the Era of Covid-19” at Undark
Looking at the ruin inflicted by the COVID-19 crazy on people who were not really at great risk, it is hard not to conclude that “science” is becoming one of the most dangerous cults on the planet.
