Yeah, Beehaw administrators said in their post that this was not really on moral or ethical grounds but just about it being really hard to moderate an influx of users from another instance. They have their registration behind an application for a reason, after all. Having a giant instance with open registration have free reign on their community kind of defeats that purpose. They also said the defederation isn't meant to be permanent, but rather it's a stop gap solution until there's better moderation tools.

users do have that choice, by making a new account on any other instance or maintaining multiple

To simplify it as much as i can, defederation should be read only. Not if(in our group/(then)they have access

The instance itself shoud be able to say it does not want content created from a subset of the internet. (Personally Its not my first choice as a freedom of speech advocate. But for them to delcare who is welcome to talk in their house is a decent compromise.)

To benefit the federation as a whole, the information and conversations taken place there should be available to the whole of the hive.

The mods could have their pie not needing more hands to manage the influx, the fediverse would have their pie with more content as a whole. ie more information available to more people at a loss of fewer availible accounts with acces to comment within restricted instances.

Defederation to me == we cant moderate the collective to our standards.

We cant moderate the collective to our standards =/= IF Y'ALL BADDIES FUCKING READ OUR SECRETS WE'LL DO SOMETHING NAUGHTY

We have the technology to find a middle ground.
