ELI5 Why does Snapchat make people ruder?

I've had conversations with the same people on WhatsApp and Snapchat and on Snapchat every time with every person they are slightly ruder more cynical,more angry more ready to take the piss

I have been added to group chats with names like failed abo*tio* which sounds like some crazy shit on snap but never on WhatsApp
