YouTube’s ad mess gives advertisers leverage for what they really want: More data

As far as advertisers are concerned, there are really only two ways to place ads online: The “open web” where you can track the ads, and “walled gardens” where you can’t.

Google falls into the second bucket.

But after they discovered last week their ads were funding YouTube videos containing hate speech and extremist messages, they suspended their business.
