This still does not make it equal between Amazon and the sellers. Remember sellers have to pay a listing fee, referral fee etc which Amazon does not have to. So with everything else being equal, sellers are basically paying a validation fee for Amazon to learn about their products, then compete with them. No one should trust Amazon in whatever business they are in.
