This here. The dirty not-at-all-a-secret is that NONE of it is profitable. It is all a money-burning, water-wasting, RAM-market-sucking black hole.
There is no road to profitability unless they somehow convince everyone to pay multiple thousands of dollars per year for subscriptions. At least that's what I keep hearing; evidence otherwise with real references, I'm open to consider.
