The fact that the protocol is decentralized does not mean that all users will be respected and have space to speak.
I ask you, for example, if on Gab Social or Truth Social everyone has the right to use their voices however they want? Obviously not.
Even if there is no censorship on the part of the protocol, there will certainly be reprimands from other users aligned with the right, as in Nostr.
I've even received death threats here on Nostr, via direct message, from a complete stranger, something that has never happened to me on absolutely any other social network. 😕
