Wait. wait.. if everything is "remote" (on Uber's cloud) then why all this drama of shutting down/locking machines? Just log everyone out and deny login attempts. My other question is, if all the data is in the cloud in SFO, wouldn't the data technically reside in the US? Looks to me like the Canadian police were hoping to get lucky. That some user wouldn't have enough time to log out.
