It's not really my conclusion - it's the conclusion from the TWN piece. That said, even though it's not a controlled experiment, the fact that they didn't have feature parity doesn't completely invalidate their experience. 80-1 is a high ratio particularly for a free product that people presumably would have expected to improve over time if they had been interested.
