Isn't this whole "tracking kids locations" an American thing, first of all? I haven't heard of parents doing this stuff in Sweden or Spain, just as two examples.

With that, comes the possibility that maybe this is some sub-section of parents in American, not all of them. Maybe middle-class and above, the people who can justify more subscriptions in their life with not much effect on their economy? Maybe some other segment(s) make more sense, just thinking out loud.

I'm not sure, but I'm guessing this is maybe not widespread among all types of parents in the US, since it isn't a "every parent in the world" thing at the very least.

What in that article made you think the psychologist didn't know parents track their children?
