In this case it's Amazon's lack of vetting third-party sellers that's causing this. Anything that actually comes from Apple will be good. Also, it won't be > 50% off, which should be a huge red flag that this is a counterfeit.
When you go to a brick-and-mortar store and accidentally purchase a counterfeit cable for your phone, it's not Apple's fault; it's the store's for opting to sell you the counterfeit.
Amazon just keeps track of the total number of items each of the N sellers sent, not which particular items came from which seller.
When a customer orders, and picks seller #1 as his seller, Amazon just pulls one from the pile and sends it, and records that seller #1 has one less item attributed to them.
This means that if any seller ships counterfeit items to Amazon, those could end up used to fulfill an "fulfilled by Amazon" order from any other seller of that item!
When the customer pissed off customer then comes and gives a bad review, it will go to their seller even though that seller may be 100% genuine.
Worse, Amazon has no idea which seller actually supplied to counterfeit item, so they act is if it was the seller for that particular sale. That seller gets dinged, and if this happens enough times he gets kicked out of fulfilled by Amazon. (And when that happens, Amazon screws him even more. Suppose that seller logically has K items in stock at Amazon. Amazon gives the seller a choice: pay to have K items shipped back at the seller's expense using a shipping method selected by Amazon, or abandon the items. If the seller elects to have the items shipped back, he gets K random items from the pool so that even if that seller only sent genuine items he may get back counterfeits that other sellers supplied. It often won't be worth it, because Amazon picks expensive shipping methods, so often the seller ends up simply losing their inventory).
There have been allegations that unscrupulous sellers have purposefully taken advantage of this. Suppose seller #1 is a big seller, doing a lot of business. You are a small seller, not doing much business because #1 has great ratings and better prices than you. So you do this:
1. Raise your prices high enough that no one will pick you over seller #1.
2. Ship a bunch of counterfeit items to Amazon to poison the pool.
Since seller #1 sells way more items than you, most of those counterfeits you shipped to Amazon will end up going to #1's customers. This hurts #1's reputation, and if you get lucky gets #1 kicked off of Amazon.

But it's not really by Apple, it's by cable_connexion and is a generic. Amazon does a really lousy job of policing what's put into the "From" field on their site - I'm surprised it hasn't gotten them sued yet.

Amazon probably allows this to be misleading, because I bet it increases sales. Ideally they would make it a lot clearer when you're dealing with a third party seller. I realize it only takes a moment to glance at the reviews and see a red flag, but I don't remember them being so negative back when I purchased it about a year ago.A perfect example is sunglasses. I don't want to go down to the mall to go get a new pair, and frankly don't even care if they're at much of a discount. I just want to get a pair of say, polarized Ray-Ban Aviators. There's a HUGE chance that you're getting a knock off or it will lack polarization. Certain things I just will not buy from Amazon because of the overwhelming odds of fakes.
It's pretty obvious Amazon just doesn't pay enough attention to the products that are sold on their website. Or they intentionally turn a blind eye. They had a bunch of listing for prescription drugs[1] and Amazon.co.uk was selling weapons that were illegal in the UK[2] for just two other examples I could think of off the top of my head. Oh yeah, and they sold cyanide, too.[3]

Also, check out on /r/surface. Microsoft's Q&A is a total clusterfuck. Lenovo is pretty bad these days too. I've had three T450s laptops in my possession at one time or the other, and all have had terrible backlight bleed.
In fact, it was just sitting by my apartment door because I was going to throw it into the dumpster the next time I go outside. Here's some photos I just took of it: http://imgur.com/a/KaQZ3. Notice the exact same markings as in this article, and the poorly aligned components. Cheap knock-off.
The killer part of this for me is that Amazon claims the product is "by Apple"; this is the page I used to purchase it: http://www.amazon.com/gp/product/B00J3ZGEE4.
Apple's apparent lack of control over their supply chain and brand, combined with their degrading software quality, is making it almost a certainty that my next computer will either be a Surface Pro or some kind of Linux ultrabook.
