If you don't want to watch the video, TL;DW is that a girl got kidnapped but was allowed to still use her Switch. Her friend saw her online which led to the proper authorities asking Nintendo for the IP address the Switch was connected to, which led to them getting the girl back.
I'm glad she is safe now, but I can't help thinking that this kind of thing will be used maliciously in the future. I don't trust Nintendo OR the FBI to act in our best interests all the time.
