Is Apple Maps really free, or do they monetize your attention and collect fees from the (suspiciously few, outside major US metros) businesses? Serious question, I don’t know, I only use Apple Maps for satellite since it doesn’t do transit where I live. But the quality level definitely feels like an “eat what you kill” product without much food, as opposed to a loss leader for the Apple brand.
