If you go just by operating income, they showed they can be profitable in Q2, and the operating loss in Q3 is fairly small (in relative terms. For every 32 dollars in revenue they lost one dollar). They haven't shown wild profits, but nobody expects them to. Any money they make has more value when it's reinvested into growing their market share and growing the market, making next quarter's numbers look better. And imho they have solid enough financials that they can make the bleeding stop if the money faucet turns off

All of that isn't very newsworthy though. We knew all that from the Q2 numbers. What is interesting is that reinvesting all their profits to make the number go up in the next quarter didn't work as well this time as it did all the other times
