Though that's a production error. Nothing to do with the inherent tech.
Maybe

Also now many modern studio mixes are poor, FM stations overprocessed with bad optimod settings, DVB with too much compression, DAB with too low bit rate and also DAB TX fed with FM TX feed (pre-emphasis and wrong optimod settings).
Also radios sold in Europe with USA FM de-emphasis.
B&Q selling lethal BC to ES adaptors instead of stocking BC lamps. A proper ES fitting has the outer to neutral (which is earthed here at the meter) and the live central pin. A BC socket has no physical polarity. Hence an adaptor should be illegal.
The people developing technology rarely have control to stop stupid applications of it. Like misuse of email, cookies, scripts on the F icon etc.
