grapie It was someone inappropriately inquiring about an app in the OS, and misinterpreting it as something it is not.
On your phone, you'll find an app called Android AdServices. This is part of AOSP:
The GrapheneOS account replied with:
Android has this hard-wired to disabled. It exists for providing the future Privacy Sandbox APIs similar to the ones in Chromium. It will remain disabled on GrapheneOS just like the Privacy Sandbox feature in Chromium.
I will also quote what @unwat said in that thread as I think it provides a lot of good information/context
No. The thing you're referring to is part of AOSP.
First, take a look at the package name. It's
com.android.adservices.api. Anything that starts with
com.android is, I believe, always part of AOSP, or at least they're supposed to be.
Since it's open source, you can read the code for this package. I found it for you.
If you build GrapheneOS yourself when pulling in dependencies the code I linked above is used.
Here's some documentation about it: https://source.android.com/docs/core/ota/modular-system/adservices
GrapheneOS is open source. You can read its code and make your own builds. There's nothing being hidden from you. GrapheneOS is also audited by others. You're not going to discover something others haven't.
Finding something and not understanding what it is/having a question about it is completely fine. Hell, it's even encouraged. Coming up with ridiculous titles such as "GRAPHENEOS EXPOSED" to try and get attention to your question, however, is not an appropriate way to engage in the community and ask questions, which is why the thread was removed.
Hope that context helps.
