I remember elon saying he is unblocking everyone apart from bot accounts on his personal twitter due to “it’s great to hear differing opinions”. He’s right, but 1. those “differing opinions” can be too extreme/offensive and that can make others feel uncomfortable and in that case it is better for them to avoid that content, 2. this change people can’t even block stalkers/paedos which is bad and 3. elon’s tweet mentioned above literally also proved that even he thinks it is a necessary feature to block some accounts.
