Real people as in people in every day life who speak freely and interact without the constraints on online communication, there is loads of censorship online.
Lots of people have an interest in controlling conversation online, MHRA, government, drug companies, people with a financial interest, the internet is a source of information for lots of people so if you can control that you can make money or get influence.
It's not a 'conspiracy', it's pretty obvious that lots of entities have an interest in manipulating the narrative in this area (even foreign governments trying to cause trouble as well) and there has been stuff in the papers about this: bigbrotherwatch.org.uk/2023/01/daily-mail-77th-brigade-spied-on-lockdown-critics/
It's a really interesting area:

There really isn't a great deal of censorship online - I'm not sure where you get that idea. Even in the 'Twitter Files' you've spoken of before didn't reveal a great deal. Even when the lockdowns were in operation, you could read plenty of criticism online.
There is no 'Big Brother' link doesn't have much substance beyond frightening headlines. The second link is interesting, but is specific to Russia. That is a quite different place to inhabit than, say, London.
The other point I'd note about the media is it is overwhelmingly controlled by the right-wing. Have you heard of Rupert Murdoch? Look up his media empire and then you might begin to see who is pulling the strings - and it is not the Left.
