The 3rd party sellers are penalized already to some degree, and Amazon has begun suspending certain listings (you can still buy them if you have the direct link, they just won't appear in search) for missing certain attributes. But IMO, it's not enough in some categories. Especially where item parameters and specs are critical for its interoperability and functionality.
