This argument’s logical error is approaching a response to a statements as if it exists in isolation.

The person you are replying to was merely offering an example to contradict a blanket statement without a factual basis, essentially that Apple does not track users because the user is already logged in. The respondent presented a situation in which that reason would not apply.

Also, your way of engaging people in this way is annoying -- specifically starting every reply with 'This argument’s logical error' and then coming up with a seems-right-at-a-glance breakdown of their argument's faults. Are you doing it on purpose to annoy people?

Starting every comment with “this argument’s logical error is…” is nauseating and hinders good conversation. Your point would sound better without it.

Everyone’s using my comment about the OP post as a launching point for their own discussions and arguments about Apple, that would have earned their own standing as top-level threads — and ideally, some would have displaced mine. So I certainly didn’t expect to wake up and see my comment earning so much attention. Hooray, I suppose. Anyways, I stand by my original point and the reiteration of it demonstrated in that chain of replies:

Unsupported arguments based on misconstrued statements and logical fallacies waste all our time here at HN. Do better, please.
