You have no idea what you are talking about. JS doesn't nearly cost as much as images, and most ad-related JS are minified. For many websites ad serving is the only profitable model. You won't make money off subscriptions unless you are one of the big players and don't have to worry about growing your user base.

I was, until recently, a paying subscriber to the NYT, and there is no difference in the ads and tracking crap they pull. So I call shenanigans on that.
