You cited rule 1, which is
The instance spreads overwhelming amounts of drama, hate or negativity.
And rule 3
The instance allows the harassment or doxxing of others.
So the question is whether the fediverse instance Threads has done the bad actions.
You are arguing for a preemptive defederation based on the actions of the corporate parent having nothing to do with content on the instance in question.
Since libsoftiktok is on Twitter not Facebook, it seems you want to be defederated from Threads based on the actions of not just Meta, but also Musk’s Twitter.
I mean it’s an argument, and many agree with it. Many instances have already defederated threads.net. but it’s certainly not in the rules cited in this post.
