Why would Google care about this? The ad uses Google's results and strips ads and cookie data, meaning they are taking from Google and giving nothing in return. Further, they use an unsupported method to scrape Google. I can see the social value of anonymizing searches but Google shouldn't bear any blame for product changes that break derivative, unsupported third party products. As a product manager, it's a nightmare when you're afraid to change (or retire an older version of) a successful product because some third party was using it in a unsupported way.
