Ioannidis even questions if ventilators are helping. He basically says without evidence to the contrary, they may be a placebo (the part about ICU beds).
And all the low CFRs he cherry picked have now increased dramatically.
"As with many interventions intended to prevent ill health, the effectiveness of parachutes has not been subjected to rigorous evaluation by using randomised controlled trials. Advocates of evidence based medicine have criticised the adoption of interventions evaluated by using only observational data. We think that everyone might benefit if the most radical protagonists of evidence based medicine organised and participated in a double blind, randomised, placebo controlled, crossover trial of the parachute."
That's not exactly a ridiculous hypothesis. A ventilator is life support; you're put on it when you're in the process of dying in hopes that something will happen before you finish.
Your lungs are filling up with fluid and your blood oxygen level is going below livable. Drain it and and ventilate which usually works much better than not doing so with pneumonia in general, or just who knows, no good empirical studies in ventilating with pneumonia related to this specific respiratory virus?
