To be fair, the Amazon page is extremely misleading with regard to this.

https://www.amazon.ca/ORIGINAL-MACBOOK-Magsafe-ADAPTER-CHARG...

ORIGINAL OEM APPLE MACBOOK PRO 60W Magsafe 2 [...] by Apple-Computers

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.

That's entirely on Amazon. There's keyword spam (for model numbers), the seller is "Apple-Computer" (Apple dropped the 'Computer' from it's name several years ago), and only has good ratings (the one 3-star rating is only about the shipping and lists no detail, and the rest only mention shipping, so they're probably fake/bought).

You're right that the page says "Sold by Mayday Dealz and Fulfilled by Amazon." I definitely missed that when purchasing, because the very top says

    Apple 45W MagSafe 2 Power Adapter for MacBook Air
    *by Apple*

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.

Amazon do seem pretty tolerant of people selling fakes. I imagine it's because it's easier to ignore than do something about but it probably hurts their brand.

Under "Manufacturer" it lists "Apple Computer," a lie made doubly hilarious by the fact that Apple changed its name from Apple Computer in 2007 [1].

Even products sold "by Amazon" can be counterfeit. Amazon lets 3rd party sellers ship their product to the fulfillment centers to be shipped out by Amazon, and if multiple sellers are selling the same item then it can all get bundled together in the same bin.

I've kind of wished lately that Amazon did a verified seller kind of thing like Twitter does with the check mark. Something obvious, not text based, completely controlled by an Amazon process. Buying from a seller with one of these marks should guarantee that you are NOT getting a fake.

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.

Amazon actually does have these sorts of restrictions but they either don't work or Amazon doesn't do a good job of vetting the "approved" sellers. Some products (and some categories) are "gated" which means you need to get permission from Amazon to sell certain items. I even think the "official" listing for Mag Safe charger is actually gated. The only thing is there are 10 or (seems to be duplicate) listings for Mag Safe charger that are ungated. Some sellers are allowed to create listings too, thus getting past Amazon's restrictions.

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]
