I don't think it matters to the principle, but rather to the practicality. It's now practical to aggregate massive amounts of data and create a privacy concern that's unlikely to have existed in the world of offline records. The principle is freedom of speech. If you tell me that I cannot write down the names of the people who came to visit me today without their permission, you are violating my right to freedom of speech.
