Someone on HN recently described the difference between profits and rents[1], which was useful for understanding this sort of thing.
TFA seems to mainly take a stance against rent-seeking, not profit-seeking. It actually has this in common with the idea of capitalism as envisioned by Adam Smith et al.

[1]: It boils down to profits being earnings you can lose if you're outcompeted, while rents are earnings that are yours even if other people would do what you do better. They're earnings from ownership rather than production/services.
I hope we all can agree that at least at this point the article jumped the shark if not earlier.
