Your points makes no sense in reference to ivermectin (as has been pointed out before)
No information is being covered up or hidden - all studies and various interpretations of them can be found online.
The scientific consensus is that there is not robust evidence for it's use to treat COVID, hence why claims like "you don't need to get vaccinated because we have something with a 100% cure rate", as are people encouraging it's use removed because it causes harm and death.
The "horsewormer" campaign was specifically designed because people are buying veterinary ivermectin, not approved for human consumption, and often experiencing side effects and toxicity due to accidental overdose.
This is not unique to coronavirus, in general, most platforms won't allow promotion of medical misinformation.
Well powered, well designed RCTs have now been set up and are ongoing, these will give a reliable estimate of the causal effect of ivermectin on COVID outcomes, allowing it's use to be recommended for or against. Again, all of this is public and you can see their pre-registered protocols online.
