"Capitalism" can be a lot of things, including things which privilege capital without regard to market freedom for labor or consumer.
Cartels certainly aren't free markets. To keep those you need policy which keeps them that way.

The problem with using 'capitalism' in discussions like this is that there isn't a precise definition of it. To some people it simply means private ownership of the means of production, to others in includes free trade, to others (and to my thinking, the most precise, but YMMV) its about the separation of management and ownership and tradable claims on the firm.
