Apple-Google contact tracing tool now usable without state-sponsored app

At least on the Google side, I've been frustrated because the app requires the GPS to be turned on, despite swearing up and down that it's not using the GPS data. The Google/Android help page that explains "why" you need to turn on Location services says that Android requires Location Services to be turned on for the Bluetooth part to work.

Q: Hey Android, why did you force Location Services to be on for your Exposure Notification service to work?

A: Because Android requires Location Services to be on in order for Exposure Notification to work.

I did not find their explanation very compelling.
