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)
The nerve of people to cry they were discriminated against for their views as if their views weren’t the original discriminator… It’s just mind boggling.
