A few hours ago, Chrome started serving an ad in the bottom of the homepage for me:  link in question is  , which is a promo for Youtube Premium, the paid version of Youtube. You can see the frustration this has caused in the top comments of the video.This appears to be served to a fraction of the users, possibly a low % AB test and/or a geotargetted campaign.It is egregious on so many levels and the implications are immense. Apparently Google thinks it is ok to serve you with ads in the application level, highjacking the homepage that you yourself have customized."Do no evil"Laughable.
