This is utterly false for Amazon UK and disprovable by 2 minutes of searching. It’s somewhat incredible to me this claim has been made with a straight face to be honest.
USB Foot Pedal is just one random search that’ll show this.
Mens fleece hoodie, audio recorder, iphone case and electric blanket are full of random named crap.
The problem also extends past these random products and into the seller market too. Even if you search with brand names for a product you want it’ll often be sold by some random new seller preferentially selected due to price undercutting.
The whole platform is rotting from the inside out.
