The idea that everyone should defederate #Threads is basically the idea that everyone who uses #ActivityPub chose a completely and perpetually surveillance-capitalists-free web space, so that's what we should ensure. This is a false assumption - and if it was true, then this wouldn't be possible in the first place. We chose to use an open protocol, knowing that anyone could also use it and reach us. And that's why we have blocking. You can't control the #fediverse, it's an exercise in futility. But you control your account and your server. You can choose what reaches your screen or your users' screens, but that's it. Other people will do what they want, no matter how angry you get. You can't force people to federate with Threads, but you also can't force them not to. Even if every known server blocked them, if people want to follow accounts from Threads, they will just make a new server that federates. No point in getting angry with reality. Maybe ActivityPub wasn't exactly what you thought. But a social network that can control who enters is definitely not a network built on open federation. To make sure Meta or Tumblr or whoever stays out of your network, create a centralized network. This is the only network you can control.
