While later studies show that HCQ + azithromycin combo might be deadly on immunocompromised patients, I don't think that it was intentionally done such that it serves as a subtle way of culling the population further. Things like this often happen in the medical world, and that's why confirmatory analysis paired with different independent researches much produce the same results or the study isn't going to be as solid as people think it actually is.
It can be repurposed to treat malaria cases, or can be sold cheap to countries where malarial outbreak still happens so as to recoup some of the money invested on such a stupid move.
And Lancet as world's credible medical journal is going to be in a deep freak after this, they might face a sanction for this, and the authors for the HCQ findings will surely be arrested for unethical data gathering.
There are reports from big names although they cannot provide the actual numbers and the hospitals which actually used the treatment successfully. HCQ is effective on other things, but not really COVID-19, which I think is a placebo since most of those patients are already receiving other treatments for pneumonia, which is the virus' deadliest complication on its latter stages.
Also, the Lancet has been in controversies big and small before, so I don't think they don't know how to handle the backlash if there ever is one.
I don't think the survival of Lancet is a major concern for most people.
Again, the issue is really simple: why was it necessary to fabricate data in order to wage a major campaign against HCQ in the media? And why are there no consequences for those involved?
These are a matter of record, not just conspiracy theories.
These questions will hopefully, directly and indirectly, unravel a lot of truth in the minds of the thinking.
