If a friend is going to leave you out of an event purely because you do not use their preferred BigTech-facilitated chat tool, then I have some bad news for you: that person might not actually be your friend. Friends don’t treat each other that way.
Something that causes some friction might absolutely lead to people treating others this way. Like if coworkers stop by your desk to invite you to lunch but you are in a meeting so they go without you. Should they have left a message? Track you down in the meeting? Waste their lunch time waiting for you? Friction matters in a social context.
For adults, sure. We're talking about children/teenagers, they're all insecure and self-conscious and don't want to hang around with the weird kid because they then become a weird kid by proxy. And the smallest unusualness makes you weird.
