There's another option for users who don't need Google Play Services or microG for notifications, etc., but still want to use Wi-Fi and cell tower trilateration to speed up the process of getting location readings. DivestOS includes only the location module (UnifiedNlp) of microG and nothing else: https://divestos.org https://divestos.org This lets you choose non-Google network location providers (which can even be fully offline), and would be a good choice if you don't need the parts of microG that communicate with Google's servers. Having said that, if you're already on an OS with microG pre-installed (such as CalyxOS), you can also keep the parts of microG that communicate with Google's servers disabled to achieve the same effect.
