If it served no purpose then it wouldn't be done. Companies don't throw resources around for no reason
I'm guessing the point is that it's diminishing returns and maybe a solution looking for a problem. Like how companies often spend a bunch of money/resources on special effects just for the spectacle of it.
Their point on sales is similar, it's not that they're selling something but that they're selling something that people don't need. Like fast fashion, it's manipulation and the only purpose is money. You can look good without following a trend, and looking good (or status) should not be the only point of purchasing something anyway.
