Wow, this is a new one I haven't heard before. Just another example of Apple selling crappy quality components and screwing the customer.
USD$80 for a VESA mount, that's a flimsy piece of crap. And Apple claimed that even though it's sold by them, it's a third-party product and they won't offer warranty on it.
If that were in Australia, they would be hauled before a court (again). What the hell? Honestly, why do people keep buying this rubbish?!
Something about that story doesn't add up. Apple sells third-party products, and Apple's own products are all contract manufactured anyway. It makes no sense to add another category (third-party but Apple-branded), but moreover, if the VESA adapter's own support info gives the Apple number, it seems to me it's an Apple product. Whatever the phone monkey thought, it was almost certainly incorrect.
The reaction to the physical condition of the repaired unit seemed also quite watered down (to me that would have triggered a massive s***storm), although after such terrible service I can't fully blame him for not pursuing this further.
If you look at the video comments, he did pursue it further, and Apple replaced the machine for him with a brand new one.
