Its pretty good deal until you consider what facebook gets out of it. Privately owning the primary source of communication that a large chunk of the world uses because its free and convenient will surely have no repercussions to end users later down the line once they end the 'grow service as quickly as possible at cost' phase and enter the 'lets squeeze our users for every penny we can to get back profit and because we know they ll take it since our service is too convenient to give up' phase.

Oh who am I kidding like anyone who uses whatsapp or any meta owned service cares about things like privacy as long as they get their free communication they are happy as peaches and will take any amount of corpo dicking
