Amazon has been blatantly copying products that other brand sold, and made them cheaper. Great for consumers if the only thing you care about it price.
Because the game is getting rigged and Amazon products will always be more prominent, no-one can compete with Amazon on these products.
You end up with less competition and less choice. Amazon can just undercut you, push you down in their listings and get the lion's share of any product type they find lucrative.
Certainly not all that bad but where do you imagine this is going if no-one else is able to compete with Amazon?
Amazon is already king and has power of life and death on countless businesses that rely on it being an impartial party so they have a chance to sell their ware.
