This is one of the things that gets missed when people talk about Amazon and fakes. It's not just about the cost of keeping nonfunctional fakes out of the product stream, it's about the higher costs of legitimate products.
Obviously, the USB drive stuffed in an SSD case is a fake. But that's not the only kind of fake going - printing "Seagate" on off-brand disks happens too, probably with much higher frequency. And cracking down on that would not just be harder, it would be a way bigger threat to Amazon's margins.
Hopefully the PillPack supply chain stays separate or separately monitored, but this wouldn't surprise me either - most cheap online pharmacies are selling real medicine at lower margins, possibly with worse quality control.

The gp merely asked for anecdotal data, nothing rigorous. By disagreeing, you are indirectly implying that the commenter is somehow incapable of telling fakes from the real deal.
In my experience, it's been because the fake one breaks down in just a few days and I end up ordering a new one, after which point I notice the important differences between the two :(
