Sophistry in the sense that according to any reasonable idea of privacy, meeting someone in public, so that they know where you are, your name and your face, is distinctly different from a private company knowing exactly where you are at all moments.

Imagine if it came out that a company had hired private investigators to follow you around, and collected a list of every location you visited. You tell someone else, and they say "if you really cared about privacy, you should not have come out in public, for instance I met you, and now I know your name, and that you visit this place". It is just nowhere near equivalent.
