Android Location API uses Google services to provide better location data using Wifi hotpsots and other devices. I wouldn't expect to be able to use Google services without Google. You don't have to use it and get accurate results without it as well.
As you can see they also provide examples of alternative apps that can be used that do not rely on Google, or you can install F-Droid and use apps from the open source marketplace that are open source as well.
This is much more than Apple, who won't even let you install apps outside their app store. While it would be nice for Google to open source their apps as well, they aren't necessary and there are plenty of alternatives and phone manufacturers who have built their entire reputation on providing an alternative to the Google experience while using Android.
