I figured the reason was not wanting to support something harmful to the customer like a fake diet pill. Call me naive for letting that assumption of even a glimmer of empathy affect my guestimation. I should have known it was pure greed all the way down and due to something like this instead.

I would take pure greed over a company imposing its morals on me.

Like I said above, they are banning foods, not companies. Foods that do exactly what the vendors claim they do. Foods that are regulated by he FDA as foods. Foods that are listed in the Codex Alimentarius.
