Mark Zuckerberg says it was challenging to censor COVID misinformation because the scientific establishment was frequently wrong, which ultimately undermined public trust: "Just take some of the stuff around COVID earlier in the pandemic where there were real health implications, but there hadn't been time to fully vet a bunch of the scientific assumptions. Unfortunately, I think a lot of the kind of establishment on that kind of waffled on a bunch of facts and asked for a bunch of things to be censored that, in retrospect, ended up being more debatable or true. That stuff is really tough, right? It really undermines trust."
