Hams take pride in being largely self-policing because this is one of the things that keeps the FCC interested in reserving sections of the spectrum for ham use.

Also, I love hackaday for their articles but the comment section there is among the worst on the Internet. You'll find more enlightening discussions on the wall of a truckstop bathroom stall.

Like I said, "The medium is the message"

One bad transmitter in your neighborhood can cut you off from the hobby. Someone who's into linux and computers can follow an online tutorial to rig together an SDR. Look at a bunch of numbers or static, shrug and move on to a different project without disconnecting that anttena breaking an entire band for all of his neighbors. Then it's on those neighbors to go build a directional antenna and buy portable radio gear and then do their own "in the field investigation" to isolate which house is doing that, then go try to explain to the random person they are polluting a band and hope the person is friendly and cooperative.

In a perfect world the FCC would do that, but getting the FCC to act on small infractions like that is a slow and long process and often goes unanswered. Especially if you're not near a marina or a federal building or an airport. So one hackaday reader can take down ham operation in an entire area because they were just interested in a weekend DIY project.

People throw that "against the law" to limit the damage. But actually getting the FCC to prosecute these issues is a challenge in itself.

I see this in basically every interesting domain now, from construction to software development to 3D printing to starting a business. There’s a huge cohort that’s always ready to jump on other people for doing something interesting, offering “friendly” discouragement at the earliest moment, often while simultaneously defending bad behavior from incumbents or their half of the political class.

I think it's mostly fear that bad actors will make government take that little bit of freedom that they are enjoying

I don't think it's about enforcing the rules (on Hacker News), as much about sharing information that others may not know.

Short story: if you piss off other spectrum holders enough, amateur radio operators will lose the leeway they get with the service including the self policing aspect.

Also, when you break little rules early (like low power transmission out of band) it makes you desensitized to breaking dangerous rules later (like keeping people away from antennas being driven with high power).
