The comments point out a perfectly reasonable explanation for why this charge might exist: One reason that drivers can specify for a cancellation is that the rider wasn't at the pickup location. Even though it's the driver cancelling in this case, it's reasonable for Uber to charge the rider in my opinion. If this is the case, the poster is still being improperly charged the fee, but it's more about the driver lying…
Conspiracy theory: maybe showing that they actually have the tools could be unfavourable to them when/if the regulations are placed?
