Well, I say... let them burn their money, if they are doing this to sabotage Bitcoin. Let the miners do their thing and let the developers analyze this threat and implement their counter measures.

We should never forget that Bitcoin is still experimental ... we still need to figure out if the tx fees will be enough to reward the miners.. once the Block reward falls away.

It is just part of the evolution of this technology and ALL other tokens would have collapsed under an attack like this.... Bitcoin is still standing.
