I completely agree with you on this. You mentioned early in your post that the ability to block instances is coming soon. As a Lemmy user that came over during the Redd-exit, there was a lot of “noise” on the All feed that has taken me some time to sift through and cater to my personal preference.

It’s for this reason why I too am, currently, against defederation. If there’s a community I don’t want to hear from, I block them. If there’s a user I don’t want to hear from, I block them. In the near future, when there are instances I don’t want to hear from, I will block them too.

While I might not want to hear from some people, their right to exist within the Fediverse should not be questioned, unless they break the rules. In which case, the user is banned/post locked or removed and we carry on living our lives.
