If we are trying to dig into the root cause? Then yes, honestly. It is Google. And don’t call them the “search engine guys”, that’s not what they are about. They are the “mass aggregation and correlation of user data guys”. Search has been a means to an end for Google for a very long time.
All those other things didn’t exist when google was developing their model. Google paved the way for the internet no longer being free, but being “free” with payment rendered in the form of user data. That in turn directly led to all those other evils you referred to. It is not an exaggeration to imply that Google is ultimately at fault for the way the internet functions today.
