This is the kind of piracy that we need to worry about because it isn't just a matter of copyright infringement, it is a matter of fraud. When you make a knockoff copy of something and sell it to someone as legit, you are defrauding them, and you really are causing economic loss to the company who legitimately makes the product. That is a good deal different from simply copying something without permission. It is something worth trying to shut down because it is a real crime with real victims.
I'm all for spending resources on cracking down on crimes where there are victims. I'm not so interested in spending lots of resources on victimless crimes.
While I agree that this is certainly a more legitimate form of copyright theft I do not agree that resources should be spent combating it or that there are any real victims.
I would consider this "the cost of doing business." If you want your copyright respected then manufacture your goods in a country that respects said copyrights, you can't have your cake and eat it too. I find that business model of:
1. Export manufacturing to developing nation
2. Force your own ideals of copyright on that developing nation
To be incredibly offensive to both the developing nation and the nation in which the manufacturing was in originally.
