> I would ask for proof people would be outraged. Google and Facebook have used their overwhelming first world profits to fund internet ventures in the third world, and no one is outraged over the actions except for the blatant colonialism the actions represent.
Well, obviously you can't prove a hypothetical, but the "outrage" suggested here isn't about for-profit companies funding charities. It's about being charged even minimal amounts for services. Google and Facebook do not charge users for their core services, so they are not good comparison points.
Users were paying for Whatsapp [1]. I believe that data point illustrates that users would pay $1/year for a chat service, but this is just an opinion until someone decides to stand up a new service and charges for it.
[1] The evolution of WhatsApp - in rumours and revenues WhatsApp had dabbled with the subscription revenue model in 2014, which amounted to charging an annual $0.99 membership fee, and earned above $1 billion in the first nine months of instating this fee. But following their $19-billion acquisition by Facebook, they came to revoke these charges, and WhatsApp was a free ride for its one-billion-strong and counting user base again."
If you think you need tens of millions of dollars annually to run a chat client at scale, no.
