It does. Dependence and independence have a lot to do with causation, as the article explains.
> Whether or not two variables are correlated and whether or not they are independent, and when one does or doesn't imply the other, is a conversation that can be had without resorting to the concept of causality at all.
Yes, but this is irrelevant. It's like saying "whether or not someone is married is a conversation that can be had without resorting to the concept of a bachelor at all".
You can talk about (in)dependence without talking about causation, but you can't talk in detail about causation without talking about (in)dependence.
