I would say "computer people" ie spend a significant portion of their time on a computer with a physical qwerty keyboard tend to use FB messenger to chat or discord if they play games.

My preference is probably steam chat. The new signal desktop is a dumpster fire.

Most people in my age group simply don't spend very much time in front of a computer. Their phone is their portal to the internet and has generally everything they're looking for.
