Yes, the situation you mention is a good example of how problems, and financial losses, domino effect into so many areas.
I wouldn't be surprised if many products we buy direct from China have counterfeit parts. But, if they work like the real thing, or if a designer designs around the counterfeit limitations, it could work out and not matter, so long as the finished product works; as far as its longevity that's another issue.
How items are counterfeited is so varied, a resistor that is just 1/8th watt could be sold as 1/2 watt, just covered with more epoxy to look bigger; a Li ion battery can have only 1/10 the amount of electroylte, so while it works, it has very little mAH. The general concept in counterfeit is Y posing as X, because X is worth more. Y could be a legitimate product re-badged to look like X.
Those failures could also be just poor manufacturing.
One problem with counterfeit is no one is being held accountable and punished for counterfeit electronic parts in at least, USA law; in money, distributing counterfeit currency holds the distributor liable, or at least subject to close investigation to track down the inevitable source of who provided the counterfeit. In drugs, the FDA will do the same. But, what of electronics? The manufacturer of the finished product is held liable for product defects to the buyer. The manufacturer in turn can seek restitution from its contractors or suppliers, but that depends on what contractual obligations were, not by criminal law. In the end, most distributors or brokers will simply refund your purchase price if you return the parts, but the consequential damages are done.
I don't know how much it costs governments or manufacturers, but I know that when products with "problematic" components reach the field and get installed, it can cost thousands of dollars to resolve the issues for customers and contractors. What's worse, it's nearly impossible to prove that a repeating component failure is due to counterfeit parts and customers expect repairs done for free (which I can understand...). One recent example that I suspect may be connected with counterfeit parts happened to a contractor I know who purchased about $10,000 worth of outdoor lighting with built in dusk to dawn sensors for his customer. Every fixture has failed at least once, and at this point the repairs have cost the contractor over $1000 and he's still dealing with repeat failures. The manufacturer claims it's not their fault and won't send any more replacements. This could end in a lawsuit that could cost 10s of thousands of dollars because one component was failing.
