Well, you don't know that. The images of the mp3 players he was selling basically look like a cheap knock off of the iPod shuffle. Apple spends a lot of money on their design and branding and it's their right to protect that investment, wouldn't you say?

This isn't the same as patent trolling.

Say MP3 Factory A gets an order for 1000 units/day but has capacity to do 1400/day. The factory still runs the extra 400/day and sells them as no-names.

Note: this is probably not the case any more with most proprietary electronics because competition is fierce enough that a factory would not want to lose a client. It does however flood the market with cheaper equivalents for all sorts of other products: clothes, shoes, wallets, etc.
