I think that the point is to make the author understand exactly why it's creepy, so that next time they write something like this, they actually see the problem.
I'm not advocating this approach. But it's not entirely off base.
It’s way off base because it’s unacceptable in civilized society to pay stalkers to harass people to make a point. Do you seriously think it is ok to hire a PI to follow someone to “make a point”? I find that horrifying.
Further this is a pro-privacy article. The author seems to have a good grasp of the situation and has communicated it well to a general audience. It even concludes with how to turn the feature off and a call to reconsider how your data is being used.
