Pre acquisition Whatsapp had 450M users. Even accounting for half the revenue of 1$ going away for payment fees (30%) and taxes (20%), that would still have been a nice cushy 200 million $ a year in almost pure profit - WA had 55 (!) employees at acquisition and 550 servers [1].

That's nothing at this scale of users and speaks volumes for the ingenuity of their staff.

The only ones driving even leaner than that are StackOverflow with just nine servers [2].

That fee wasn't really enforced. I was in India at the time and no one paid because no one had credit cards tied to their account. Everyone still used WhatsApp just fine.
