I like stories on instagram because its not intrusive, unlike messenger, facebook, and whatsapp. The reason I still use snapchat and pretty much boycott stories that get handed out by facebook is because it feels like they're using dark UI practices to force it down my throat. Why does messenger open up my camera when I launch it? Why does it ask me to put pictures that I send my friends on my public story? Why do peoples stories take half of my messenger screen? It's really intrusive, and incredibly annoying.
