It depends on your view point. For Bitcoin to succeed it must be able to withstand what some view as an "attack" on it. If bitcoin is vulnerable to this attack it doesn't deserve to last, it needs to be fixed, tested and tried again. All of these cryptocurrencies are still experiments and advocates equate changing the code consensus code like patching a 787 in mid flight because of how much value is dependent on the network working. The miners fork winning will be a bad thing if you value the decentralized aspect of the currency and want bitcoin to succeed. Not everyone does.
