OPs point, I think, is that wasting the user's time is part of the point of the code. This specific code seems partially meant as a punishment of the user for using an adblocker.
Their goal, quite clearly, is to prevent (or at least heavily discourage) adblockers. This is one attempt to detect them, and maybe in Chrome they have a different detection mechanism so it doesn't show the same behavior.
It would be a particularly foolish move on their part to push Chrome by punishing everything else right now, while they are in the middle of multiple anti-trust lawsuits. It makes me think that is unlikely to be the intent of this change.
