The issue is if an electronic device with a 15A plug has an internal failure (short) and draws MORE than 15A. The purpose of the breaker is to trip, and a 20A breaker won't trip until it senses 20A of current. So the 15A outlet, or the 14AWG wire (normal use on a 15A circuit) fails and causes overheating which leads to a fire.
