Funny thing is when you google Home Depot or Paramount Plus you get ads served by Google as the first result. When click on it Google then shows you a 404 page. I wonder if they'll get a refund on their Adwords campaign.
There ought to be a law that essentially says if ads are “paying” for content, there must be a flawless link between ads and content such that the system can tell if the content is available (or detect after the fact that something was not delivered properly). And then, based on that, it either is required to ensure the ad never plays (since the content cannot be delivered), or that the user must be compensated in some way (e.g. we see you were forced to see an ad but got nothing so we are crediting $1 to your account).
