It's actually everything to do with quality. Google wants to direct buyers to the product source, not the hundreds of resellers. Rewriting descriptions may work for now, but then some other update will come along to knock resellers back down.
Sell unique products or start counting your days.
Tell me something, what store sells the Nike Zoom Kobe Bryant VI. And is Google going to have a one result page from now on?
