My opinion is that the correct response to Fedi Garden (or any other instance that says they won't federate with an instance that federates with #Threads ) should be:

"You go to hell!"

This is no different than if you throw a party and invite several people and a few of them say "we won't come if certain other people you've invited are there." If you are polite, you might say "Sorry, we'll miss you." If, however, you think they are just a bunch of assholes trying to tell you who you can or cannot associate with, you might tell them to just f**k right off.

I get it, they all hate Zuckerberg, but they're not punishing Zuckerberg. If anything, they are driving Mastodon users to create Threads accounts so they can communicate with their friends there, rather than communicate with them through Mastodon. Zuckerberg couldn't care less. It is your USERS you are hurting if you block Threads.

I get defederating an instance if they are doing something really bad. But wanting to be able to follow Threads users in and of itself is not bad. Zuck is arguably bad, some other individual Threads users are bad, but the bulk to Threads users are probably not bad and I for one would like to be able to read what they post without having to set up an account on Threads. And if the #FediGarden people don't like it, they should be told to stick their #authoritarian nonsense where the sun don't shine.

Fedi Garden to Instance Admins: “Block Threads to Remain Listed”
