A software developer made a Chrome and Firefox extension called Knockoff that automatically hides, grays out, or filters products from sketchy brands on Amazon, which highlights just how many shady brands are on the platform and how commonly they show up on searches for basic items.
They’re usually knock offs. They aren’t trying to present themselves as an item made by Versace or whatever, but they knock off someone else’s idea or product.
That’s still a knock off by most any definition.
