Who is surprised here? Google makes money by spying on people. Everything they make is designed to make money. Search history gathers what you are interested in. Android and Chrome vacuum your physical data and more. YouTube both gathers your interests and might become a serious advertising platform someday. Gmail vacuums up what Android messaging misses. Google Ads, Fonts, and Analytics catch anyone who isn't using Chrome with the help of webmasters. Every major Google product is designed around one purpose: knowing everything about you.
I have used Firefox for years and years because this is obvious to me. Google shuts down divisions that make a lot of money all the time. Yet somehow, they are just spending ungodly amounts of money on all this "free stuff." Please. I don't care if you watch a 30 minute YouTube video on how to set all of your Google settings in just the right way for them to graciously not upload live video of your face. Two patches later you have to do it again. This is all while trusting this highly sketchy company to honor its settings. It's like trying to set the perfect contract with a demon or wish for a monkey paw. The real way to win is to not do it.
