No company is going to put chokes on every cable if they’re not needed to pass FCC. Why would they? Would you want extra chokes on every cable just in case a ham operator might use the product somewhere?
Note that this author isn’t claiming the device breaks FCC limits, just that it emits enough that his highly sensitive radio could pick it up.
It’s not reasonable to be mad at a company for shipping a product that meets the limits. This guy just wanted something lower than the official limits because he’s tuning a radio to that frequency right next to it.
Not only does the device feed high-frequency signals into your power wiring, it can get noise from it like motors turning on or off and spiking the voltage.
It's only a problem if it's a problem. If they'd done proper filtering inside the device maybe it's ok.
