Assuming an average valuation/yearly revenue ~= 20 it means that for $3.5bn the should make $175m a year. If they have 350m photo shares a day (!!!) this number seems very well within their reach. They can even afford to monetize less aggressively and thus more user-friendly. I think it's one of these cases where numbers are so huge that they work in their favor whatever they do.
