Maps worked great for their primary purpose of finding your way to some designated location for hundreds of years without built-in analytics and marketing info. When the latter is getting in the way of the core function (eg finding out what street you're on), something has gone badly wrong. Lately Google maps won't show your own location if you have Google location services disabled, even though pretty much every phone has a GPS built in. The map is no longer the product, data about what you're doing is the product.
