No, the single tenet of capitalism is "make profit". Capitalism doesn't care how you do it- lying, stealing, manipulating, indoctrinating, forcing, polluting, killing, it's all good.

For any corporation in the long run, a small edge translates into exponentially more capital, and since capital runs society, you can simply buy up the competition, or force them out of business.

Monopolies are not an issue for capitalism, they are an issue with capitalism.
