The principle point that Malone is making, and he said this several times in Joe Rogan's podcast (deleted out of YT and probably Twatter), is that informed consent and free speech are being trampled by the #SharterJoe thugs.
Having been involved in drug development (from a QA perspective, not as a scientist) for about 25 years, from what I could gather based on Malone's talking points to Rogan's very targeted questions, Malone understands the drug development process. What he knows about mRNA and whether he was in the weeds on that technology, and whether he's exaggerating his claims, I'm not going to comment toward because I haven't looked into it well enough.
But all of that does not outweigh his central point -- the fraud, deception, lies, and data manipulation employed by the #SharterJoe thugs completely run counter to our core principles of free speech and informed consent.
