Users publish their messages to multiple relays, and they can be followed by others on multiple relays. The idea is that if a relay starts censoring, then users and their followers can choose different relays, so the system as a whole “routes around censorship”. At least in theory.
I interpreted in a similar yet different way. It is not just that users can choose a non-censoring relay but that users are connected to many different relays and so it does not matter if a few relays censor stuff
This is an interesting detail to me and may just spend on how the community grows
In Mastodon each server makes their own decision on who to censor. Functionally it's grown into a bit of a hard mentality with entire servers being censored if they don't go along with the larger group
