No doubt! 
Maybe not hidden, but definitely bad, in my opinion.
Opaquely slurping up, tracking, cataloguing, classifying, and storing the private characteristics, behavior, and location of most of the people on Earth, using it to increase their revenue and for who knows how long, all while exerting undue influence on the rest of the browser market, the design of web pages and applications whose creators are enticed to include their tracking and analytics tools, including in mobile software, frequently manipulating access to information as a result of said tracking… Of course, you can choose not to use specific Google applications, but Google’s influence still permeates everything digital. (Facebook is just as bad, if not worse.)
Google has created some very useful services, of course, but we all know for what ultimate purpose. Development and web real estate aren’t free, but maybe we need some other monetization paradigms besides user exploitation in extremis and ad infinitum. (And I don’t know what those could be. Lol!)
