AntennaPod is a great example of privacy being interrelated with censorship.

AntennaPod is a great podcast app because not only is it open source for privacy, but it also uses RSS feeds to get content right from the sources to avoid a single company overseeing all your actions.  Now, RSS feeds are not as censor-proof as Nostr notes, but at least they decentralize the data sources to prevent Apple from having full say on what gets banned.
