Would you mind linking to something pertinent, in order to add to the discussion? What does she say? Where does she say it? Why does that appeal to you?
In this case, the opening of the person's Wikipedia page probably sums it up right away:
> In the article, Khan argued that the current American antitrust law framework, which focuses on keeping consumer prices down, cannot account for the anticompetitive effects of platform-based business models such as that of Amazon. She proposed alternative approaches for doing so, including "restoring traditional antitrust and competition policy principles or applying common carrier obligations and duties."
If you want a raw view of her views on anti-trust: https://www.yalelawjournal.org/pdf/e.710.Khan.805_zuvfyyeh.p...
In one of the podcasts she dives into the history of anti-trust. She talks about how after Standard Oil we convinced ourselves everything was a monopoly and stifled a lot of innovation, which led to some reforms later and the anti-trust we have today which are demonstrably too permissive. She has picked on Amazon (as a wider corporation) quite a bit, but a lot of it has to do with the practices of their ecommerce division and the extent to which Amazon can compete with it's vendors. Basically, she believes there's a middleground to be found between the two anti-trust time periods and that it's important to be concise in how we do that. You can see some of her specific criticisms in the article above.

I highly suggest "The Separation of Platforms and Commerce" as that's the one that resonated with me, having worked in the startup world.
