He explicitly and clearly disagreed with the claims, and argued against them:

> What [AOC] meant was that it's impossible to get that rich without doing something bad — without cheating in some way... The reason [my founder's] startup was growing so fast was simply that users loved what she'd built. So she could feel from her own experience how wrong [AOC] was. She wasn't exploiting anyone. Exactly the opposite in fact. The reason her startup was growing so fast was that she and her cofounder had been working their asses off to make their users happy, and as a result the users had been telling their friends. And that gets you exponential growth.

To any honest reader, it's clear he's saying the system isn't necessarily dishonest, and that it's possible (if not common) to rapidly earn money in the system by simply creating things of value and selling them to willing customers.

Except he says nothing about the system, he only talks about the founder.
