This paper seems to mainly suggest that the suppression is happening on the internal platforms that Meta's employees and content-moderators use, for discussions, rather than that they're censoring what I would see an an end user?
You're right, this report isn't about the actual censorship of end-user content, but that was also quite widespread. Zuck even himself admitted how the US government would pressure them to censor certain things, but he discussed it in the context of COVID. Similar things happened about Israel-Palestine as well
