The article seems to go directly from "this piece of software talks to all the sensors and isn't well sandboxed" to "Google has directed this software to profile and surveil users" without actually providing evidence to support that leap. Is Google Play Services sampling your location so that it can send it in to Google HQ as part of a secret location tracking operation that runs without user consent or knowledge, or so that it can detect if the device has been stolen by the cops and use its proprietary ML model to activate anti-theft mode to protect the user's privacy?
If we can actually show mismanagement of user data by Google Play Services, we need to shout it to the hills, because those sorts of scandals are important arguments for increased privacy protections. But we need to actually find that mismanagement occurring, not just assume it must be because Google wrote the code and it isn't open source.
