I sometimes wonder how the people behind these things feel about themselves? Do they feel bad about essentially stealing but suppress it when they see how much money they can make? Or do they just have no conscience?
The same goes for any kinds of scammers, AI spam bot owners, etc.
I don't really see this as equivalent at all. Scammers, spammers and botnets etc. degrade the quality of life on Earth for many people with 0 consent. You could say that this product is disingenuous but ultimately it really only has an impact on dumb rich people. As a more general rule, it depends on the level of deception and the claims being made, but ultimately you are simply offering a product into the market. The other examples you mention are an extreme nuisance in general, but also have huge negative knock on effects from things like mitigation and general behavioral changes.
So it's really small potatoes to me. If some idiot willingly buys a cord for 50x the market price, that is largely on them.
