I feel we are in a crazy world with chat/messaging applications and it has been going for a while. It's like if I have a mobile phone carrier I can only call numbers who are with that carrier but nobody else. Or email people only within gmail. The walled gardens of every single chat application (FB Messenger, Viber, Telegram, Signal, Skype, +probably thousands of others) makes users install several chat applications on their phones or computers in order to keep communicating.

My question is actually two-fold - do you think there should be a regulation from somewhere (EU,countries, app stores...?) that if you develop a chat application (I understand that's vague but law usually is) you need to be able to provide a way to chat with other chat applications (via xmpp or whatever).

And the second part is - is there already some initiative that I am not aware of that is attempting something similar.
