It's not 'censorship of factual information' for a private service to choose to put health warnings against or delete fact free claims of HCQ as a miracle cure. Indeed "healthy living" supplement hucksters are ridiculed and kicked off platforms on a regular basis, even when some of the claims they make about "healthy living" have a tenuous connection to fact.
We don't change the parameters of science to pretend that people insisting that a pandemic isn't a threat because self-administering a moderately dangerous drug is effective prophlaxis are presenting "factual information" because the people doing so are supporters of politicians rather than pill vendors.
All of which is tangential to my original point which is that "HCQ is a miracle cure" became a meme entirely divorced from the tentative (and probably manipulated) evidence of therapeutic benefit well before attempts to shut it down or the Surgisphere "study", so I can't imagine why more blame is apportioned to them than the public figures making evidence-free claims about it from the very beginning.
