How do you feel about Threads?

I heard it will be on the Fediverse. Is it true? I heard it had 30 millions users registered on the first day. Wtf. The whole Fediverse doesn’t even have 10 millions users. I heard it will not be available in Europe, yet. I visited www.threads.net and I don’t know if it’ll be the Threads instance to the Fediverse....
