Capitalism simply means assets are owned by individuals and operated for profit. The implementation details depend on the individuals (and their values). Nothing about capitalism says anyone or thing needs to be exploited, cheated or monopolized.
It shouldn't be so taboo to discuss flaws in the capitalist system.. The article itself is a very raw exposition of a characteristic of it that I imagine is understood by people on both ends of the political alignment spectrum as a damaging thing, not that it couldn't not be.. I think the discussion matters because reality matters.
However, I do want to strongly note that "profit" here often gets re-invested into the company to develop new and better products (or use the money to damage others, aka the "jerk" behavior). This no longer is "profit" then, by definition, but now has become overhead in the company.
Meaning, "for profit" does not equate to "for filthy riches".
