I left Facebook on 1 January 2012. Never used Instagram and stopped using WhatsApp on 30 April 2017. I haven’t missed it for a second. Some people asked me why I don’t have Facebook / WhatsApp anymore. I have a few answers for them:
It became clear that Facebook broke it’s promise. It promised it would not connect Facebook and WhatsApp. And would not use any WhatsApp data to improve their advertisement platform.
I spent too much time in WhatsApp, it became unhealthy.
I absolutely hated the group conversations, and you are kind of mandatory to be part of it and be responsive.
