How long have you been part of the fediverse? (A term which tends to not be capitalized, by the way. *nerd snort*) It’s not about you getting to interact with every instance using just one account. It’s about putting the power into the hands of ordinary people. Including the power to associate or disassociate with certain people, communities, and content. That includes an admin’s ability to go “I see you’re not sufficiently moderating your instance. We will defederate until you’ve taken steps to ensure your instance sufficiently moderates with common-sense rules.”. Whether that is due to some content policies or to block an instance from which a ton of spam originates.

Just how with email a provider can choose to block or automatically mark-as-spam any email coming from a server they don’t trust, for example because it’s a known source of spam. It’s actually how a lot of the internet works. And it works as long as well-intentioned people are in positions to make such decisions. And if a server or service goes rogue, they get the equivalent of defederated.

Incorrect. I’m fine with instances that host a variety of content. Including stuff I don’t want to see.

However, I’m allowed to join an instance whose admins take a stance against bigotry for example, and therefore take better care that such content isn’t allowed to freely go through their instance. That way I and a thousand of other users don’t need to all block the content they don’t like manually. It’s my instance admin’s choice, and my choice to go with their instance.

This was perhaps a bad example. Though there’s the possibility of posts not being marked for NSFW that should be (and the instance not enforcing such), and ones that are mostly harmless but still labelled as NSFW for one reason or another. One person’s NSFW is not the same as another person’s NSFW. Feel free to replace the example rule with something else.

If you want your freedom – whatever that means to you – you go to an instance that represents those values. Admins that run their own instance get to decide how they moderate that instance. And that includes blocking (or defederating) whole instances, communities, or individual users. You don’t have to sign up to one that does something you don’t like.

Besides, you don’t seem to understand the importance of moderation. If it wasn’t for the ability to defederate, we’d have tons of fake instances with fake users creating fake posts. Not to mention people going out of their way to make others feel miserable. Do they have the right to spew their hatred? I have my opinion, but it doesn’t matter. I happen to also have the right to join an instance that has a policy to take care of that stuff so I can browse for things that actually interest me.

Allow the admins of the instance to enforce their rules?

Say you have an instance with a “no-NSFW” rule, for people who don’t want to randomly come across NSFW communities. Their admins could take care of the curating of rule-breaking NSFW communities without having to resort to defederating from the entire instance. This doesn’t have to be an outright block but just a filter that could prevent the community to show up in “All”.

Falling in love? In this economy?

It’s a lot more legally dubious for them if you defederate. If your instance willingly connects and shares data out of their own volition, it’s like that instance giving permission. If an instance blocks communication via the ActivityPub protocol outright, what are the legal grounds for Meta/Facebook to be able to freely access that information? Even if it’s posted publicly to view.

As an example. I can have my own website and post some info there, write articles, have contact information. People can view it. Companies can index this information and make it available to search. But I’m guessing it’s not legal (or at least less so) to be collecting that information to process and sell. Companies can do that so easily because you agree to it in their terms of service.

(But hey, IANAL.)
