Anybody that doesn’t know the code their device is running is a fool to trust it by default. Even knowing the code well, devices are compromised all the time. Yours seems like the lone sane opinion here.
Just as if my location/microphone were able to be physically turned off on my phone I would not have to trust that someone isn't always listening in on me. If I can't do that it is not unreasonable not to trust it. There have been plenty of instances of these things being abused.
