I've ordered clothes, furniture (desks, chairs), books, supplements, rugs, and probably a few other things. Everything shows up, seems to be exactly as claimed, is functional, and has worked.

So my initial question still stands on what people are complaining is rife with fakes and knock-offs. It seems to be quite niche electronics (huge hard drives, computer components, etc)

And if the knock-offs are so good (in your game example) that the end user can't tell the difference (and no one else can either), what does it matter?
