That's the weird thing about WhatsApp though.. back when they bought WhatsApp it was still a paid service and a lot of people actually paid for it and it was on its way to get to a billion active users.
After that acquisition, they made it free for all and started chasing the $$$ with WhatsApp for business. And ads. No idea which is more profitable anymore. I think they'd still be able to monetize it more with WhatsApp payments and those ads in status updates. I'd definitely like to know what the numbers are looking like these days..

It was, but it was very cheap (UK pricing was £1 a year), and I believe had lots of free users anyway. My guess is that the revenue wasn't worth pursuing.
