Honestly, since all that really matters to Uber is $$ and being forced to deal with the law (and even then only barely), Gett should just sue them. It's clearly illegal (putting aside differences between NY/CA law) and it proves the point in a way they'll be forced to notice.
That's certainly Uber's stance, but it's not "obvious" at all :
> [OP] "In some cases, Herman said the Uber employees waited until the cars had showed up to cancel the order. Uber said the orders were all canceled immediately."
Deliberately waiting until the last minute to cancel a ride would certainly indicate intent to disrupt. That Uber is denying having done this should not exactly come as a surprise.
Sure, if they actually did that. At the moment this just seems to be Gett's word against Uber's, and since doing that would not in any way aid Uber's goal of harvesting phone numbers, I'm not inclined to believe Gett just on their word. The most benign explanation is that the drivers simply didn't check their phone to see that it was cancelled until they'd arrived at the address.
You're just making assumptions about Uber's goal.
It's Gett's word against Uber's, and the latter is the one who has admitted engaging in immoral and possibly fraudulent activity.
