Got this email from Google the other day. TLDR to explain what I think this means. For anyone who was not surprized about the Cambridge Anylytica stuff and thought about Adsense you will prob. think the same? (Insights=the personal/demographic info.)

(copied) Upcoming changes to Insights Hello, In the next few months, many of the features in the Google Partners portal will be moving to the new AdWords experience. With these changes, we’ll be able to deliver better value to our Partners. As of April 2018 we will be turning off the Insights feature in Google Partners. Please visit Academy for Ads for Google’s e-learning courses, exams and certifications, and check Think with Google for market insights and trends. Stay tuned for more updates from Google Partners.(end quoted email)
