My comment was about the usage of the term unfalsifiable, which means something specific that was being misunderstood.

I don't know whether they are charging more when users have credits in there account. It seems plausible I guess.

Here are some plausible reasons why it may not be the case:

- If Uber's analysis determined that the best price to charge to maximize profit is independent of whether or not the user has credits

- Because predatory practices would generate bad press and push users to competitors, which would reduce profits
