I don't want to just copy and paste my previous comment, but this isn't how companies at this size think about declaring profits. See https://news.ycombinator.com/item?id=47347993

Hence the comment you replied to saying "they print cash". You'll find a lot of big companies work this way: high free cashflow, because they earn a lot more than they spend, but then the spare cash is either reinvested or paid out via share buybacks. Declaring a profit isn't advantageous compared to the other options available.
