Fake 2TB USBs on Bezos shopping site

Opening one up explained it all- it was a cheap "USB flash drive" PCB/internals hooked to a USB A 2.0 to USB-C conversion board (so that it looked faster/better than it is). Amusingly, they used masking tape to hold some pieces together inside the drive.
Just, completely made for fraudulent purposes.
The brand is made up, the "storefront" name changes periodically (was VHSGUUDS CO. and now CSGARH CO.,LT), and the listings are super generic.
Amazon clearly doesn't care. Maybe a prosecutor bringing legal action against Amazon would be the best way to make them care.
I support legal action against the companies selling the products too, but they tend to disappear and reappear under different names, and are likely all located in China, which I assume makes prosecution more difficult.
Responding to your edit: this is not "private companies doing the job of the government." If there are fraud and/or consumer protection laws on the books, then companies need to follow them, and they need to face legal consequences when they don't.
