I think those are good implementation concerns. Maintaining two separate websites isn't really an option under the supposed regulation, that's still one company being a platform and a manufacturer. The second option seems alot more likely to be allowed -- but now, at least you've created a market for that information and it's not just Amazon that has access to the data. Not sure I understand why it would treat the those products preferentially though -- unless you're bundling selling that information with product placement fees, which doesn't seem to be related (or necessary). I would assume product placement would be another revenue stream for the platform, like it is now for brick and mortar retailers like walmart
