Your quote from their link is a boilerplate minimum restriction that applies when no further restriction is provided. Most places, especially "sensitive" ones have even stricter limitations. Go ahead and try and fly a drone 500 ft above a military airbase, you'll meet some fun people and have plenty of free time to pick up a new hobby.

Nuclear silos are generally not that sensitive, because they are all 60 years old and everyone can identify them on satellite imaging, but if you fly a drone near one, you will definitely be surveilled by some security, whether you know it or not.

If you bothered to read it's a ~3-mile radius from the plant, but sure. If you want to test your theory, go ahead and buy a drone and try flying it only 300ft above a nuclear power plant. As soon as you're found out, you'll promptly be arrested (if your drone doesn't already automatically shut off due to GPS geofencing).

Can you please make your substantive points without snark and swipes, and please not post in the flamewar style?

The HN guidelines ask you not to do those things, because they degrade discussion and we're trying for something else here.
