#WhatsApp is not a messenger, it really had become the next generation of #Facebook. It has all the pieces in place: masses of users, massive groups where anyone can join, #advertising, etc. The only real difference is that they have to put some of the logic in the client app, because servers see message #metadata, but not content.
As a company, Facebook only knows how to do #SurveillanceCapitalism so it is no wonder that they turn everything into #addictive spying machines to #track us.
