Ideally, the fediverse will help people in censorious countries access information their governments don’t want them to see, but I am not too optimistic, I used to think that about the entire Internet and look where we are now, governments around the world are very much managing to control the spread of information on it.
I intentionally didn’t register on big instances like lemmy.world or mastodon.social in order to avoid being part of obvious places to censor.
