First there was big Tobacco then there was big sugar and now there is big pharma. Studies have ulterior motives so I vote for #2.
Here is the subject lines to the FDA pronouncement against using HCQ in an outpatient settings (where advocates say it should be used: when a person first get sick.)
FDA cautions against use of hydroxychloroquine or chloroquine for COVID-19 outside of the hospital setting or a clinical trial due to risk of heart rhythm problems
Does not affect FDA-approved uses for malaria, lupus, and rheumatoid arthritis
But it is ok for malaria, lupus, and rheumatoid arthritis.
The heart issues showed up when infected patients were nearly dead and of course they would be in a hospital so this pronouncement will cost lives since the advocates of Zinc/HCQ are correct and it has been demonstrated around the world as effective.
WHO is adding to the death count.

Here is a link for a report about how many studies lead to false conclusions. But studies are not needed because there are many who have had this illness, some died, some survived without the experimental medication. So that is the control group. Zelenkos numbers is the experimental group and since his numbers are good we need to follow his plan, or a similar plan that others provide.
A you tube commercial is not a study. People are welcome to do as they see fit but there are currently no studies that show effect of hydroxychloroquine in mild disease or prophylactically. Hopefully some will be completed soon
