Neither did my laptop, desktop, or phone. I use Linux and GrapheneOS
GrapheneOS is a significantly more complicated and less accessible option for most users compared to a simple paper notebook, which is the context of this post.
But if you want to go this deep, then yes, maybe your phone using your custom OS never introduced Gemini or Copilot without your will. It is however running a Qualcomm modem firmware you can't control and is phoning home, regardless of your GrapheneOS settings, with your GPS coordinates and other data you can't read, at any time. Don't worry, with tech we can always find a malicious feature that works against the user, regardless of how deep you want to dive.
