I thought this looked interesting. Both are trending downward. Could it be because of their adblock detection scripts?

If it is, wouldn't it imply that there are similar effects to websites not allowing people with an adblocker, as there are to mistreating the "tech" person of a family or a large social group? [That is, just as the techie boycotts your products, the adblocker user will not link to your website on their social feeds, which might have allowed a non-adblock user to click]
