I favor Amazon on this. No company has a "right" to sell on Amazon, so they're free to go and advertise elsewhere. If they want to use Amazon's enormous market presence a few concessions seem reasonable. Expecting Amazon to stock, advertise, and manage your product while you work to undersell them is **you** being unreasonable.
Eh it's pretty anticompetitive since you need Amazon to get any sales, while you won't be able to make money even if you go through lengths to specifically bid against a.co ads and pull a customer to your own website.
