The sneaker manufacturer told me that if they find that Pumas are being pirated, or Adidas are being pirated and their sneakers aren't being pirated, they know they've done something wrong.  So it's very important to them to track piracy exactly because of this, and the people who are buying, the pirates, are not their customers anyway, because their customers want the real deal.
このスニーカー・メーカーによると PumaやAdidasの海賊版があって 自分達のスニーカーに 海賊版がなければ 商品に問題があると 思うそうです　― ですから海賊版を 追跡することは重要なのです そもそも海賊版を買う客は そのメーカーの 顧客ではありません 本当の顧客は 本物を求めるはずです
