Users think they really grab the attention of oncoming traffic; true, but they make it hard to see anything else.
Having been blinded on a MUP myself, and seeing a lot of rider with overly-bright headlights, I have come to the conclusion that such riders think of their headlights as a force-shield that will protect them from oncoming cars, so the the brighter the better. 
Personally for nighttime riding on my mostly well-illuminated suburban and urban roads, I prefer a flashing light at a low setting pointed at the road surface, and two flashing rear lights, for redundancy and dyssynchrony.
