There’s no point in talking about Whatsapp as a tiny company charging $1 to a small percent of its user base. No one had any intention of keeping it that way.

I also don’t think billionaires like the founders saying they regret stuff after they’ve become billionaires from Whatsapp’s sale should count as a counter argument. I doubt they’d be fine giving back their billions for a few million a year salary while being worried about what their future will hold.
