True, but not many people will understand that. I think it - or rather the information - may become a catch 22: maybe Nostr and similar technologies could be free (as in freedom, regardless of if as in beer or not) ways for people to discover this, but they will first need to know such things exist, and also experience a reason to use them. For obvious reasons, it's in centralized social media platforms' interest to shadowban the information as hard as possible. I'm actually surprised that for example Reddit's r/nostr still seems to exist.
It may also be in governments' interest in the future (or already) to force social media to shadowban all information on Bitcoin's benefits, and things that may lead people to finding out, such as information about Nostr.
I realize I'm still doom-and-glooming about things that aren't certain, it's probably a result of two decades of privacy mainly going in the wrong direction... I just don't have much hope that people in general are going to have any strong desire and/or ability and/or knowledge, or whatever it is that has been lacking in the privacy matter, to make any difference in any other important matter either.
Anyway, I'll listen to the episode some time in the coming week.
