Yea. I also find it hard to believe that WhatsApp wouldn't be profitable with $1 per user per year. There is a lot you can do with $2bil a year.

I think I read that Brian Acton called out Sandberg on that once. That it wasn't just about profitability, but greed.

They were supposedly charging that, but the first year was free, and then every time you were close to running out of free time you would get x more free months. I chained those free months for years until it became completely free. So it was actually free to use.
