The fact that governments do actually engage in censorship doesn't mean that everyone who posts about the real or possible risks of the covid vaccines get their posts censored or that people whose posts about the risks of covid vaccines were removed, were removed because of goverment censorship.

Even in the case of twitter. Here: https://twitter.com/reuters/status/1536697529454272512

There's a tweet about the risks of covid vaccinations. If the government, twitter, or both were censoring discussion of the risks of covid vaccinations how does that exist? How do the countless other uncensored and easily searchable posts that do the same thing exist?

Isn't it more likely that if a post about the risks of covid vaccinations does get removed that it's for a reason other than because of an attempt to hide information about, and prevent discussion of, the risks of covid vaccinations?

Who do you think is telling people they can't talk about the risks? We're doing it. It's talked about all the time everywhere. It's researched every day. The media reports on it to the public. Nobody thinks that there aren't any risks. Whatever oppression exists in the world, "preventing people from talking about or learning about the risks of covid vaccines" is not an example of it.
