its not censorship, and its not 5 randoms. Those 5 people mute option only affects people that follows all 5 of them simultaneously. If I mute you in my feed it’s not censorship just because “the decision of a single person dictated the blocking of a message”. Muting an user is an expression of one’s opinion, and if you want to dictate who is not allowed to mute someone in their social mesh you are the one enforcing censorship in the network.
