Tricking customers into buying things they otherwise wouldn't is the core concept of adtech.

If you insulate humans from the manipulative dark patterns (though agent intermediaries), it's possible for them to spend less, spend more efficiently, optimize out information-asymmetries that are profit centers for entities like Amazon. Of course Amazon will fight this.

Realistically the agents will inject their own dark patterns. Whoever owns the glass owns the revenue stream, for they have the ultimate power to replace anyone else's revenue stream with their own. Some TVs detect ad spots in video content and overlay ads that pay the TV manufacturer instead.
