So, what they are excluding are the micro-vendors that heavily use Amazon and E-Bay, and may not maintain their own websites. Periodically I encounter mainstream online vendors also using Amazon or EBay, especially for closeout and overstock specials.

They are also implementing the UMAP/MAP (Unilateral Minimum Advertised Price) policy. It sure sounds like price fixing to me. But, it would also affect companies like Nashbar. So, Nashbar would be required to sell at above a certain price. Now, they might be able to play around with shipping a bit to compensate.

I've also bought Continental branded tires on E-Bay, pure auction (minimum?). Anyway, they ended up being about $80 a pair with several bids. Low, but not insanely low.

My Clement tires also came from E-Bay. The previous owner had unsuccessfully attempted to mount them tubeless. So, they had zero miles, but had some dried goo inside. So, can Michelin prevent someone from deciding they don't want something and reselling? I've even bought new tires from TPC (small business that normally sells used stuff on E-Bay).
