Automatically creating a shadow account for everyone on Instagram?
Even allowing people to follow that account?
Sounds like they really wanted to push Threads out the door in a big way.
I don't think I'm missing any point. Have you used it? They're owned by the same company. Threads is separate but part of Instagram. Other than the user name being reserved on Threads in case the Instagram user wants to sign up, there isn't an account created. If you try to search the name of any of those accounts in Threads it doesn't come up at all. (Edit: mistyped a word)
