なぜ Android（OS） から離れる？
Play Services holds broad permissions and sends data to Google in the background. Account suspension can break parts of the device experience.
Googleの限界・リスク
- • Play Services embedded in the OS—wide device data sent to Google
- • Preinstalled apps and settings nudge users toward Google products
- • OS updates depend on OEM and Google; older devices lose security patches
- • Non-custom-ROM devices offer little path to reduce OS-level Google dependency
