Google wasn't tricked, it's intentional. Their business model is generating money from clicks. It's not showing you best results for what you search for. It's showing latest news, tragedy, and what people talk about. 10h old news? OLD, BORING. New shiny 2h young news? YEA, more clicks, clicks and more click, more ads, more clicks, more revenue. The sponsored content online must be constantly changing and adapting to new information to generate more profits and more clicks and keep people clicking and visiting and searching. Don't forget that it's not only sponsored content, but also targeted content with user tracking, because clicks count, on one day they will show you news to annoy you to generate more searches and clicks, on another day they will show you majority of stuff to calm you down. Keep clicking.
