I'm not addicted. I hate it. It's a horrible chat app. I especially hate the lack of threads (or at least pinned posts) in groups, I have to scroll through pages of garbage to see that important announcement. I also hate that it's linked to my phone. If I want to use it on my computer, because I hate typing on phones, it needs my phone to be always connected.
I'm stuck with it because everyone else is using it.
