Truckers are the biggest demo but it's sold under a generic category.

There's no listing. The story is made up.

While the general premise is true (big company will try to rip off small company), Amazon doesn't have the magical power to get around patent law and the economic penalties are fairly harsh, which is why most companies don't do it. And no war chest of tech patents is going to get Amazon around a patent in the trucking industry because the inventor of the trucking gizmo couldn't care less about whether Amazon patented the right to make Alexa speak in tongues.

It's possible, and likely, that Alibaba vendors decided to rip off the product, but again...patent law is a useful tool for those who use it, and Amazon can be held liable for the sales of infringing products on its storefronts.
