> (b) An amateur station shall not engage in any form of broadcasting, nor may an amateur station transmit one-way communications except as specifically provided in these rules;
No, it's either one-way or two-way. One-way is usually prohibited except in a few case, two-way is usually fine unless it violates one of the prohibitions like encryption. Your two-way communications using ham radio are public, not private.
A two-way conversation that involves short periods of what's technically "broadcasting" is very different from "tune in at 10pm to hear me talk for an hour".
> Broadcasts are also prohibited in ham radio.
Wait what? Isn't any message either broadcast or private?
