This is literally email spam. The whole point of the article is a lie designed to sell a ridiculously dumb product which absolutely does not work as described. This is arguably worse than fake news. Because it's spam!
Note: I'd appreciate a law that penalizes this kind of lying. I admit there is potential for abuse, and that we'd need a good legal standard for getting something obviously wrong as opposed to just getting something wrong. But this has a massive social cost, and I think it's not unreasonable to balance out those massive social costs.
Here's an idea: many news outlets sell access to their news. I should be able to sue them if they give me something that is not news. I also think there is an implied warranty for news sites, and so you should be able to sue even if you aren't paying. That's a legal theory that would work okay, probably.
