I had a non-tech acquaintance mention he got called to his son's school because his kid "got busted" with "a hacking device". Based my friend's vague description, it must have been a Flipper Zero. The kid was initially threatened with expulsion but I assume someone from the school with a clue got involved and it was knocked down to a 3 day suspension. Still excessive but a survivable lesson.

So, if you have kids just be aware that while we all know these are just SBCs with some neat SDR peripherals, the first Google hit a school administrator sees may be some mainstream media article with a click-bait headline.
