How nostr can't be banned by governments:
Nostr is an open source protocol. There is no single point like a person or company that the government can strong arm into doing what they want done with nostr.
Shadowbans: your freedom of speech has consequences and you can get muted by most of the community leaving you shouting in a void or replies going unseen. That's about as far as shadow bans go here.
Influencers: Can still pay their way to the top here but it's not by how much money you have, it's by how large of a following you can bring to nostr after you join.
Chances are if your in Influencer elsewhere, you'll be one here too and accepted by the top folks here on nostr. Like Ian Carroll for example.
Government propaganda: can still make its way here and does imo. Humans susceptible to grp think are responsible for the spread of government proaganda. For instance all the smart free thinkers here thought political voting would work after trump said he'd free Ross on day one after showing up to a bitcoin conference, even though political voting has a proven history of not working in favor of the people, and everyone was saying to vote trump. He didn't free Ross day one and now these people look like fools for succumbing to government lies and propaganda posting about "does anyone have a free Ross day 2 shirt"
Moral of the story: use nostr with caution and always think for yourself.
Freedom comes with good and bad actors.
