So following your analogy (which I'll state upfront is a poor one), where do you think the government attorney is wrong? Because from where I sit the government attorney, if not completely correct, is at least on the right track. Other companies can piece this together (how else do they know that you are logged in somewhere else?), and I would be shocked if there isn't some means on Twitter's backend to do the same.

And from reading the transcript, it would seem that Twitter's objection is about analyzing the data, as opposed to simply providing it.
