Reads like a lot of socialism to me.
I understand the B&M vs internet debate. B&M will never fully go away but only the strongest are going to survive. Free markets need to be Free, not Free* (some restrictions may apply).
Actually, the question is whether or not MAP requirements by manufacturers are price fixing or not.
As a private manufacturer, if I go to a store and tell them that I am willing to sell them my product at $X price, only if they agree to my reseller terms, then, they have the option of agreeing or not.
So, as the private manufacturer, do I have the right to not sell to someone who won't abide by my rules?
The question of who gets to make the rules is up in the air, and there are plenty of devalued brands which are fighting commodity levels, and lowering their quality, as well as their customer service to meet demand, while other companies demand a maintained level of margin, and insist upon keeping that margin in order to allow places with a higher level of customer service to maintain that level of product and make a fair profit on it.
While you may think that the online etailer should have unlimited access to all products, it is typically the right of businesses to refuse to do business with anyone as their own choice, and this has been declared one of the reasons why they can refuse to do such business.
