It is constantly surprising to me that 'free speech influencers' are not all on nostr.
There are people who talk every day about the problems of censorship and centralisation but refuse to take an active role I'm creating or participating in free and open internet they claim to want.
They probably don't know about Nostr to be honest, but if they've heard about it and not immediately dove in, then that's an entirely different story.
In my opinion this is not a valid reason.
There are people in a promenant role who can correctly identify the problems but seem to do minimal research into fixing it.
They can put together well researched YouTube videos or do endless hours of podcasts on Facebook and twitter cencprship but they can't google "censorship resistant social media" every few months to see if there is an alternative. I just did and nostr was the first result.
Hell, I knew about Nostr back when it WAS being proposed as a Twitter and Mastodon alternative back in 2020.
No (usable) clients, just open code available for anyone to poke at.
If you have heard of them, then they are already successful in getting the attention (and possibly payment) they want on their current platforms. Probably a bit of rationalization about being where their message can be heard.
