I don't know if it is censorship or customization. Is a group or community supposed to be the same as a public town square where nothing should ever be censored, hidden, blocked, deleted, removed, invisible, shadow banned, etc, etc, or should a Steem community be more like a private house where you bring in your friends for a meeting? So, should a group admin be like the house owner with the ability to rule the house and to kick out people or hide things in order to govern the conversation and everything within the given house? If the house is supposed to be public property, then no. If the house is supposed to be the private property of the admin, then maybe yes.
