> And yet it's absurd when, to follow the law, you need to do testing on even unintentional radiators (with few exceptions) with a digital clock higher than 9 k

  This is a situation where the law and the actual practice is so diverged that we've basically just enshrined selective prosecution by the FCC. Small volume manufacturers just try to design well and roll the dice because (almost?) no one is spending four figures on an accredited lab to do emissions testing on a device that sells a few dozen or couple hundred units per year. Some try to find a way to indicate that it's used only in transportation, that it's industrial/commercial test equipment, that it's a peripheral device or sub-assembly and not a finished end-user device, others just realize that the FCC isn't going to bust down anyone's door because a device not emitting harmful RF doesn't have a testing certificate on file.
