Ioannidis didn’t do the study, and there is widespread criticism of it. It may be withdrawn.
But the infection fatality rate being much lower than the case fatality rate is no secret; it is widely know, as you’d know too if you get away from propaganda sites and looked at proper reliable sources. For weeks now I have been estimating the infected proportion of the population from the death figures, because only a small proportion of infections are confirmed and therefore counted. IFR and CFR are different things.
If you had chosen to discuss with Squonk rather than fight and advocate you’d have known all this too.
