worries me a lot more than
a 2012 post on the company’s blog that boasted of how Uber had tracked the rides of users who went somewhere other than home on Friday or Saturday nights, and left from the same address the next morning.
Obviously Uber has this sort of data, and it can use it in various aggregated ways. What's more important than demonstrations of what information they could pull out of this is how serious they are about protecting it from access, either from people who want to buy that information or employees simply snooping around. I don't care if someone uses my data in an aggregate way to do something (e.g. facebook) as long as I am not personally identified.
