Like I said, if any of the chargers or cords I have received from Amazon are counterfeit, they're good enough counterfeits that I don't care. My iPhone, iPad, and MBP all charge just fine, still have perfectly fine working batteries, have never had any issues with the electronics, and nothing has caught on fire after years of use. The headphones I've bought from Amazon sound great and have given me no issues. The lightbulbs I bought from Amazon light up my room just fine and last a long time. The SSD I bought is blazing fast and has plenty of space (confirmed by multiple diagnostic checks). The clothes I have bought are comfortable and fit well... And if any of these things weren't true, I am confident it would take me extremely minimal effort to return the item to Amazon and buy a replacement.
Obviously counterfeiting is a problem and in an ideal world there would be no counterfeiting at all, but I remain unconvinced that it's something I have to worry about materially affecting my experience as a customer buying stuff from Amazon.
If at any point I see any evidence or warning that the products I purchase from Amazon cause any material amount of risk to my person or property, I'll reevaluate. In fact, there definitely are some things that I prefer to buy outside of Amazon for such reasons, like climbing gear or medicine.
But as for stuff like chargers, I've had more experience that the easily-frayed genuine Apple Lightning cables, or the classic exploding Samsung phones, are more of an electrical fire risk than anything I've bought from Amazon, counterfeit or not.
For chargers, I've had some seriously laptop-destroying ones. For phone voltages (ignoring fast charging), it isn't that big of a deal, but USB-C PD laptop chargers I am extremely hesitant to buy on Amazon.
Almost every memory card that isn't Samsung EVO PLUS I've received has been counterfeit.
