So that your abuser cannot obtain real-time information about you via integrated accounts.

> It's not like Google is going to sell your tracking data to abuser.

No, that's exactly the fear. With enough disclaimers and third parties involved, a motivated, highly intelligent and rich attacker with the right connections could get that information.

Here's an article explaining why one should care: https://privacypros.com.au/privacy-hub/articles/dv-safe-phon...

The tl;dr is that you can either share this data by accident through some sort of "locate my family" app, or because your abuser gets access to your Google/Apple account (for instance because you're signed in on another device they have access to).

The threat model here can be: domestic abuse victim flees a situation at home in a hurry, stays signed in on a computer. Abuser uses the sign-in on that computer to track their phone, figures out they're staying at their aunt's place.

Yes, you can avoid this on a regular Google phone as well, but that requires correctly configuring it (and a lot, such as location and search history, can be re-enabled remotely!). If you're running Graphene you are protected by default, rather than compromised by default.
