WhatsApp was definitely my favourite messaging service at first. Being able to call and connect to friends for pretty much free was really useful and nearly everyone had it.
However as you have outlined the main downfall of whatsapp was it being bought by facebook and now they have this huge void to fill and what better than breaching millions of peoples privacy for their own monetary gain.
I can't wait until the day where everything is based off the blockchain and we can have a more equal, distributed and safe future @kurtbeil
