Absolutely defederate from threads immediately from anything threads related.
Threads will collect any and all data they can about users disregarding which server they are on, and not agreeing to their business practices.
There’s a reason they are not in the EU, including NI despite being in UK. And that’s probably because their practices are illegal, and don’t respect the rights of their users according to EU regulation.
The second Lemmy federates with Threads, I’m out of here.
