That doesn't force Nike to do anything, and Nike gets properly paid for each product sold. Trademark aspects likely are covered by the first-sale doctrine (=as long as you actually sell legit Nike products, you can advertise them as such).

Amazon's saying "Hey Nike, you'll be selling through us whether you like it or not". And it's forcing Nike to actually explicitly sell through Amazon if they want to retain any control whatsoever over the product listings.

Sure, but that's the same with every other reseller: if you want more control over how they sell your things, you need to make a deal with them about it. Just because a seller is larger than others it's not suddenly a monopoly abuse if they legally resell your product. Saying "I don't want you to resell my stuff" is generally speaking not a right you have as a manufacturer (you might have leverage to stop misleading advertisement or misrepresentation of the product though).
