Thank you for posting this link! I've had no luck trying to get people to take the attack presented by the original paper seriously over on Reddit [1] and hadn't seen this critique yet. Still, I would have liked to see a more technical rebuttal from Mr. Felten, so I hope he posts more in the near future. I don't see how being a fairweather miner like he describes is an issue. Pools already employ strong protections that prevent pool-hoppers from gaining anything. I started implementing a simulation of the attack last night in an attempt to reproduce their results.
