@thaodan @blenderdumbass >There's a big intersection of hardware only legally verified software is allowed to start
I would actually like to see a single law that says that.

In reality, although some radio regulations insist on restricting what a transmitter can do, there is no requirement that the software used to implement signalling has digital handcuffs on it.

>it very much makes sense that only verified software can run which could disrupt others or even risk the lives of people.
Proprietary software that cannot be fixed in a life critical device is arguably much more risky to the life's of people than software that can be fixed via physical access (you can sabotage such machines in much worse ways with physical access).

There is no reason for any hardware to refuse to run any modified software anyway - all it needs to do is display on the output that the installed software does not pass the signature check, which would allow the hospital staff etc to investigate (while not much investigation is going to happen if yet another machine has stopped working - it's getting thrown out).

>but better than someone disrupt some radio signal.
When it comes to interference, it is *always* proprietary software that causes interference and not free software.

Proprietary software is known for breaking transmission rules by increasing TX power above what regulations allow and that cannot be fixed, as the software is proprietary (this is very common in 802.11ac AP's although "Open"WRT supports a few of them and on them decreases TX power to the legal limit).

Modern radio equipment is expressly designed to handle interference now anyway, so there is no reason why it shouldn't be a free-for-all on most bands with maybe an agreed upper limit on TX power (this is pretty much already the case with proprietary software transmitters, except some of them are transmitting in excess of what the TX upper limit would be).

If someone wants to disrupt some radio signal, they'll grab a microwave and disable the interlocks, rather than spend dozens of hours fiddling with some software transmitter.
