Any brand who cares should dislike Amazon. As a consumer, at least half of anything I order on Amazon is fake, and Amazon gives no indication of caring at all.

Hence, if I order a pair of Nike shoes on Amazon, there is a good chance I receive an absolutely inferior product and blame it on the brand. Once that damage is done, I - and a perhaps a portion of my friends - will never buy the brand again. Ever.

It’s seems to me that this could be much worse than shoes.

For example, how am I supposed to know if the Sandisk flash drive I bought was directly from the manufacturer, and not a 3rd party who is part of an industrial espionage effort? How about a Yubikey?

This is likely not just a problem with Amazon, but it sure would be nice if they gave me an option to buy things directly from the oem, guaranteed.

For Samsung MicroSD cards, Samsung has a tool you can download that authenticates the card. I don't know the specifics of what the tool does, but presumably with proper use of cryptography techniques, it could be made nearly impossible to circumvent.

A caveat - I used the tool and it said the card was genuine. Afterwards I put it back in my dashcam, and the dashcam said the card was bad. I just had to reformat it in the dashcam and then it was fine.
