Vaccine-makers sought to shape content moderation actions at Twitter. Stronger, a campaign run by Public Good Projects, a public health nonprofit specializing in large-scale media monitoring programs, regularly communicated with Twitter on regulating content related to the pandemic. The firm worked closely with the San Francisco social media giant to help develop bots to censor vaccine misinformation and, at times, sent direct requests to Twitter with lists of accounts to censor and verify. Internal Twitter emails show regular correspondence between an account manager at Public Good Projects, and various Twitter officials, including Todd O'Boyle, lobbyist with the company who served as a point of contact with the Biden administration. The content moderation requests were sent throughout 2021 and early 2022. The entire campaign ... was entirely funded by the Biotechnology Innovation Organization, a vaccine industry lobbying group. BIO, which is financed by companies such as Moderna and Pfizer, provided Stronger with $1,275,000 in funding for the effort, which included tools for the public to flag content on Twitter, Instagram, and Facebook for moderation. Many of the tweets flagged by Stronger contained absolute falsehoods. But others hinged on a gray area of vaccine policy through which there is reasonable debate, such as requests to label or take down content critical of vaccine passports and government mandates to require vaccination.
