Me too, but I still can't stop using WhatsApp, it's the most popular IM app in my country, and only a small percentage of my friends cares enough about their privacy and digital freedom to switch to an alternative.
I care about the amount of time I spend on those platforms and the amount of garbage I consume on them. Whatsapp is just a messaging platform, not one that provides an information feed to consume. I kept twitter because it's short and limits the text I could post to someone about something, which also limits the desire to do so because a tweet is ironic, informative or sarcastic, but cannot ensue a good and lenghty discussion (though some people try that, I cannot bear to imagine doing so)
