Google maps stalking is indeed bad and I hate it but you can easily disable it by not running Maps in the background.

Honestly Android allows me to tune out of the internet business model a lot easier than iOS. Just dive into permissions and install a system wide adblocker. You can even bypass the app store.

I always have location off but my old coworker used to leave hers on. One day after work we were waiting for the bus she took a picture of some grafitti near the bus stop. A minute later she got a notification from google asking if they could, I can't remember if it was, tag the picture or add the picture on google maps or both for the gas station next to the bus stop. It was fairly creepy, i'd never seen one of those before. She started turning her location off after that.
