I was in your camp until the weight of the discussion convinced me otherwise. I learned regression as an advanced statistics topic, and it wasn't touched on in my (beyond awful) AI class. However... If linear regression is being used to predict the next value in a dataset, and the caliber of the regression improves as more data is gathered, then it counts as machine learning. For all I know, Netflix could be improving their picks of my movies with a grand regression.
