I was wondering where this claim even came from.

It's from a comment, not even the article or the video it's based on. It's just the same internet rumor mill that's been going around for years, but more official because someone quotes it on an discussion on a news article because someone posted it in the comments of the article.

Anyone who's tried to test this theory has not proved it. A few claims in support forums are more likely to be people's guests or family just connecting it to the wifi.
