This. One of the first things you learn in an introductory statistics course is that a positive correlation (or, as it is even more vaguely quoted in this article, lack of a negative correlation) doesn't by any means signify cause and effect.

Again, this. It isn't "New Windows OS is released, demand for Mac increases," it's "Hey, it's Christmas time, so demand for EVERYTHING increases."
Ultimately, this article is a waste. I would like the time I spent reading it back please. kthxbye.
