You're assuming these things are mentioned. "Hi, I'd like to book/confirm an appointment with Dr. Jones." doesn't leak information about "abortion".
Yes, these things obviously depend on what information is transmitted. The point, however, is that metadata more reliably transmits sensitive information than does "the data".
yes it does.. just look up who dr jones is; is the metadata going to say "this lady is getting an abortion" ?
1. The conversation may or may not contain information pertaining to an abortion.
2. The metadata (namely: "it's an abortion clinic") inherently contains such information.
The point is that metadata is usually the more interesting data.
no it doesn't, it'll contain a phone number to a clinic, then you'll have to look up what kind of clinic it is
you're telling me the receptionist answering the phone at the clinic won't mention the name of the clinic when someone calls?
and stick to objective points and don't fault me by calling it nitpicking because your argument falls apart when basic critical thinking is applied to it
