I haven't seen the studies you're talking about, but the FDA claims Ivermectin hasn't yet been proven effective, and the WHO says it should only be used in clinical trials. But assuming for the same of argument you're correct, your claim is that the only available source of knowledge about Ivermectin anywhere would have been videos which were deleted from Youtube, making it impossible for anyone to avail themselves of this miracle cure due to Youtube's "censorship", and that there are people who avoided taking any of the other existing and effective COVID vaccines and who died of COVID as a result, and that Youtube is therefore to blame.

That's pure speculation based on an already far-fetched premise.
