I don't think privacy and censorship resistance are necessarily inversely related like this, such that something being more private must be less censorship resistant, and things that are more censorship resistant must be less private.

You can have things that are neither very private at all or censorship resistant, such as Twitter and Facebook.

You can have things that are very censorship resistant, but not very private, such as #Nostr.

You can have things that are both censorship resistant and private, such as Keet.

And I would assume you can have things that are very private, but maybe struggle to be censorship resistant, which the founder of SimpleX seems to say applies in that case.
