When you first set up the device, you get a screen that asks you if you want it on or off. It tells you that it's used for targeted advertising. Every time you update your Mac to a major software version you get a window pop up with those questions too (along with stuff about Siri, telemetrics, etc). That's not the same thing as having it on by default and hiding the setting in a menu somewhere. But that's how your comment reads. You probably just ignored the questions and closed the window. There's a lot of things you can fault Apple for, but I wouldn't consider that one of them.
