Can you provide an example of a product where Amazon enjoys a monopoly (or even something close to a monopoly)?
We should not be shepherding a new tech baron era, but enforce competition in markets. Competition should be the highest thing we value in an economy. This experiment of consolidations, mergers, and acquisitions since the 80s has been disastrous. We're reaching the point where we should break up nearly every multinational conglomerate, they've abused too much and suffered too little.
aga98mtl pointed out this isn't actually true in practice.
It sounds like you're describing a different form of potentially anti-competitive behavior, which is not the same as the one yonron accused Amazon of.
Some of the world's most innovative products were designed by subsidized Business Units. The original Mac Lisa wouldn't have been developed if it wasn't propped-up by the success of the wildly-popular Apple II/IIc. Even though it failed, there's not a single nerd on either side of the Apple row that would call that anticompetitive or a mistaken product.
