I've also been told learning too much about linux or the nuclear reactions in power plants or bombs puts you on a list. I just assume I'm on several.

Learning too much about Linux puts you on a list? That can't be a thing. Isn't Linux itself entirely a civilian project?

The rationale mentioned was it was under the subheading of people interested in strong encryption, people who care about being unobservable might have something to hide. Maybe it's a good list? People who you might want to ramp up a new Bletchley Park? Probably not.

Whatever you do, don't broadcast on the airwaves, as in pirate radio. That really does put you on the list.

I don't believe they have the people to monitor those that know 'how to use grep' and put them on a list. It stands to no reason, government civil servants are rarely from the top drawer.
