Good post. Points out the real need of other methodologies like Customer Development and Business Model Generation for finding profitable product/market fit.
Leancamp's a good example of this too. It has product/market fit, and passes the Net Promoter / Sean Ellis tests. But the business model itself isn't easily sustainable or scalable, which is where I've had to place my attention the last few months.
