Switched cold on them. Basically I told people okay am shutting down WhatsApp, after that hack that allowed third parties install application on your device through bug in calling protocol, and told them am switching to Signal. If you want to reach me, either SMS or Signal. And that’s it. Most people I talk to added Signal to their ever-growing list of chat applications.

But if you use anything they already have, they won’t change the way they talk to you. There has to be inconvenience involved.
