Yes, and the point is that we are destroying the environment by selling stuff that has no real usefulness, this isn't really a great future.
I bought a suitcase there and used it to travel the world. I would definitely consider it "useful".
The problem isn't that they sell no useful items, they just sell so many items that even if a small percentage (it's not a small percentage) are destined for landfill then they're creating an astonishing amount of waste.
The article mentions that they only buy returned overstock items from manufacturers at steep discounts. So this stuff was getting made anyways.
Not quite true. From the article:
> Almost half of its products are leftover goods that manufacturers couldn’t otherwise sell.
