I personally do not mute just to not listen to other’s opinions, we are having this discussion for instance. Yet I understand that it maybbe the case for others. The current system is quite useful, instead of manually blocking a lot of accounts the client can just automatically mute using a web of trust system. But it works no different than languages for example. By learning one language you are, by the socia web you connect to, “muting” everyone who speaks a different language. Yet you could learn and translate if you wanted to. It’s not censorship for anyone.
