Indeed, but crappy switchmode supplies radiating RF hash into the house wiring is a problem that affects low band radio reception. I spent several months 30 years ago tracing landmobile interference to the switchmode PSUs on new 140Mb/s digital microwave equipment in the building next to the landmobile station, then designing mitigation/suppression for the problem and handing the fixes back to Fujitsu.
Domestic smartmeter RF hash is almost as bad as the hash that smartplugs intentionally inject into the wiring.
