You have to be able to show damages you incurred and assign a dollar value to them to sue people.
That doesn’t work at all for a something that sells your bandwidth to a proxy service. People wouldn’t even be aware that it was happening they weren’t told.
Not legal advice.
(It would surprise me greatly if we as a society let these gadgets be sold openly from here on.)
The cybercrime raids happen when they run into someone who looks like a hacker and has a lot of computers.
Its incredibly obvious to anyone applying any thought at all to this that its a malicious to sell a product that labels itself as a TV streaming stick which is in fact a paid for relay server with the money made from providing the internet connection to a random third party unrelated to the person who bought the thing without ever telling the customer.
While there would be oversight, it is highly unlikely that a person opening a home improvement store would perform any meaningful safety testing. They simply would not be qualified. The oversight would lay in selling certified products, pulling recalled products off the shelf, and (perhaps) removing products if there is a reason to suspect safety issues.
Now consider streaming sticks. There are safety standards for the physical device but, to my knowledge, there are no such standards for the software itself. Heck, there aren't even standards for the engineers who work on the software. One can make highly prejudiced decisions based upon the country of origin. Perhaps there are even good reasons to avoid products from certain countries. Yet the lack of standards also means that products from trustworthy sources can be suspect, since all it takes is a management decision to change things.
Or if I open up a gas station and allow any company without oversight to sell "supplements" through my shelves and cops arrest me for selling heroin, I don't get a free pass.
Why should amazon or Walmart get a free pass just because they sell more items?
