No one I know uses WhatsApp either (thank fuck). No one wants to download another app that now they have to juggle between different sets of people. I’m a software dev and even I hate all this nonsense of ten different messaging apps. On any given day I might use slack, discord, Zulip, Google messages, imessage, and matrix. Two is too many, this is just ridiculous. Absolutely no one in America wants to be using this many apps to communicate. Which is why most people just use the default.
