I'm not sure these are opt-out. I think they're opt in. I have the latest iPhone (well, it was the latest until this fall ) on the latest non-jailbroken firmware and have used an iPhone since the 5s. I go to coffee shops often. They're basically my second home. I also use the default Apple maps when navigating, and have location turned on for a few services, including find my iPhone. My phone definitely knows where I frequent. I recently moved cities and my iPhone recognizes my new "home" even though I never updated it. (it's where I sleep a lot, I guess). Still, I have never gotten these location-based alerts, nor have I ever opted out of them.
