David Zweig’s December 2022 thread described pressure from both the Trump and Biden administrations and examples of overbroad COVID enforcement. He highlighted Martin Kulldorff’s views on vaccination priorities and prior infection, and an internal review finding only one of Andrew Bostom’s five recorded violations valid. These are concrete examples to examine, not a reason to dismiss every complaint as partisan grievance. The thread also describes occasions when Twitter resisted pressure. [1]
His larger criticism was that moderators sometimes treated departure from public-health guidance as proof of falsity. Guidance combines scientific evidence with policy choices: who should be prioritized, how much risk is acceptable and how uncertainty should be communicated. A contested recommendation should be identified as such. Equally, possessing a medical credential does not automatically validate every statement a person makes. [1]
Actual vaccine harms should be stated plainly. CDC recognizes a rare causal association between mRNA vaccines and myocarditis/pericarditis, most often in adolescent and young adult males after a second dose. Reporting that risk is legitimate. But a verified rare risk does not establish that every illness after vaccination was caused by it. This is why a useful audit checks the specific words, evidence and date of each moderation decision instead of sorting speakers into permanently trustworthy or untrustworthy camps. [2]
