Some counterfeiters are of course, shit, so it’s pretty easy for most of us to notice when we order a board game and all the text on the cards is 20% off of centre. But you have to figure that somebody out there is capable of taking a high resolution scan of the materials and printing it without making obvious mistakes like that.
And like... in Apple’s testing over 90% of Apple accessories (chargers, cables, etc) were fake. Obviously they’re outwardly convincing enough that 90% of people aren’t returning them despite dropping $35 on a USB cable that’s worth about $4 from a third party. A lot of the counterfeit chargers are outwardly identical — unless you tear them apart to see where they’ve cut corners and risked burning your house down you’re never going to know.
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?
But that's just my personal preference.
You've completely skipped over "90% of Apple products are counterfeit". They are not niche, are not easily discernible, and pose a safety hazard.
