It seems the publishing industry has reached a point where they're so cash-strapped and so beleaguered by ad fraud, that they feel they have to run a ton of code to:
- fingerprint you
- detect ad-stacking and other scams
- detect how long or if the user has looked at the ad
… all of which leads to the familiar "I just loaded a news article, why is my fan spinning?"
If you're already chewing up the user's CPU to try to make money, cryptocurrency miners sorta feel like the logical conclusion.
