That's good for Amazon, but from a consumer's (and responsible vendor's) perspective, until a bad actor vendor gets caught by this system and kicked off Amazon along with all the reviews of their counterfeit/bad inventory, consumers have no way to protect themselves. A consumer on Amazon cannot even protect themselves by ONLY ordering from Amazon's own seller listings. I've done that myself and ended up with used/repackaged stuff sold as new. It creates a natural "market for lemons" experiment on Amazon. I can't imagine that is healthy for Amazon in the long run.
