I've never had a Facebook or Instagram account in my life. But I do use WhatsApp because it's the main way most friends and family communicate (Australia).
I would not be happy if I found out I suddenly had a Threads account that my friends could follow without me even signing up, just because I use WhatsApp!
What a nightmare this whole thing is turning out to be. I mean, imagine being the CEO right now. You want to seem strong, you don't want to back down, but every day the chaos seems to get crazier.
Does that person who has been pre-followed then get a notification to join and respond/follow back?
Because that would be a great way to boost the new service exponentially.
