I have explained it this way:

You've had a long, hot summer and it hasn't rained for months.  Suddenly it 
rains and it pours in through the roof that you hadn't noticed had lost a 
couple of slates.  Do you blame the weather or the builder of the house? 
Similarly, your neighbour can say that he never had interference before, but 
then, he wasn't aware he had a problem till someone fired up a radio 
transmitter next door.

The rarity of interference from a radio amateur to/from a neighbour is why 
plasma TVs, switchmode supplies, hi fi systems, video recorders et al have 
such poor emc performance - it's a cost that is statistically unnecessary to 
the masses.
