Certain drugs now, specifically hydroxycholorquin, ivermectin, and the vaccines, now have teams. One negative effect of this is that researchers are highly disincentivized from researching them once they have been picked up by a team, given the consequences of publishing results one team or the other doesn't like. The net effect is not just the manifested stuff like that in the article, but more importantly a chilling effect where only researchers who have an axe to grind take on the subject, resulting in bias and a feedback loop where distrust grows and polarization around the drug's efficacy continues.
It'd be fascinating if it wasn't so depressing.
