Although I agree that ICE block and its various sibling apps and spinoffs are important and do accomplish something meaningful, it's certainly not a "fake thing" that many of the world's foremost experts on the relevant topics were censored with regard to epidemic response.

Facebook's treatment of the BMJ investigation of the unblinding of the Pfizer trial (which of course, turned out to be spot-on) was absolutely shocking, and is just one of the many instances of "ICE block-level" censorship.

(In case you need a refresher on the Facebook-censors-BMJ drama, I summarized it a few months ago here: https://news.ycombinator.com/item?id=46232902 )
