the message to take away is?
Computing devices of all kinds have their weak points - in some cases lots of them - despite the manufacturers trying to squash them. There are people whose job it is to find those weak spots.
As a result, those people (employed by your government) with a desire to subvert a particular computing device probably have some technique at their fingertips to do so.
caveat
In some cases those people are on your side and subverting someone else's device is in your interest. In some cases they are on your side and it's not in your interest
In some cases they are not on your side and it is in your interest
In some cases they are not on your side and it's definitely not in your interest.
Isn't life complex
