Running isn't any long term solution. That is why people are mad. Censorship follows where the people are. If a critical mass of people goes to mastodon, that is where the advertising and censorship will go. Just like how it went to reddit after a critical mass went there.
The comparison doesn’t even make sense. Reddit is a centralized platform, not a protocol.
I won’t say it’s impossible to censor something like nostr but good luck with that.
