An example would be a productivity app that only has a flip switch for High or Low productivity. Whenever you need to be extra productive, just open the app and set it to High.
Some users were utterly convinced that their machine was running faster than ever before, when in reality the malware did nothing other than begging for cash payments. Often the opposite by slowing down the machine with continuous pop-up advertisements and other nasties.
Placebo apps that make your Internet faster are as old as the Internet itself though. I am guilty. In my defense, that was 20 years ago.
The fact that placebos are effective is precisely /because/ they're effectively tricking whatever badly-understood connection there is between our thinking and our body. I imagine that there are degrees to this: 'tricking' ourselves to be productive by deciding to clean our house instead would generally not be called a placebo, whereas taking a sugar pill that lifts us out of depression probably would.
But fundamentally they're just the same thing on a spectrum: an improvement as a result of something that we /know/ should not be effective by understood, biological pathways.

Really it's not much different than selling a wooden cross that will "protect you against satan".
(Unless it is passive - aluminum foil or a mesh cage, which is perfectly legal.)
Therefore it's false advertising.
OTOH, the reasoning for poor construction of these devices is probably similar to the reasoning for poor English in 419 scam emails.
I do find it interesting the desire to harm/screw other people over and feel no remorse. Like those scams getting busted in certain places eg. fake virus support. People show up to their actual office and do the scam like their 9-5 haha... Idk crazy. I sometimes wish I had that malintent vs. just being a passive people pleaser. Like I'm sorry of my existence. Meanwhile guy jaywalks across traffic to me and asks me for some money so he can go to McDonalds... Idk. Conversely I see a legitimely homeless person and I offer them money, they refuse.
I'm not sure this is the driving force here, especially when your description sort of fits the worst psychopaths, and I can think of other principles these people live by which aren't necessarily driven by such 'evil' forces. E.g. desire to survive (==food/shelter) which in modern society usually translates to desire to earn money, see an easy way to do that, feel remorse but ignore it.
Alos, after having talked to so-called tinfoil hatters, it seems that a large part of them genuinely believe all these theories (well, or were extremely good in tricking me into believing they believe) and as such also believe they can actually help people so from their point of view it's not a desire to harm or screw over but rather to help. As crippled as that might seem to others. I.e. do not underestimate the power of the human mind to play tricks on itself, or mental problems in other words.
Surrounding yourself with a strong electromagnetic field should help you shield against electromagne... forget it.
Clearly you haven't read the advert, it's a 'nano-layer of quantum holographic catalyzer technology'
