The point of auto switching multipools is to intelligently direct your mining rig's hashing power to the most profitable coin at any given time. Which coin the pool mines can change many times per day, presumably faster and more accurately than any person can do it manually.

That is what they claim to do, and that is in fact what they do... and they do it well. The problem is that when they do that, there are significant repercussions. I don't argue that there should be no multipools, I simply think that it's OK to have coins whose stated goal is ASIC and multipool resistance. That's a differentiator, which is good in a free market.
