Masternodes are a human controlled point of failure that has never nor ever will be incorporated into a serious cryptosystem. These systems are fragile enough without excessive parts that serve no real purpose other than to funnel money into the greedy hands of early adopters.
There's no technology in existence that you can't cherry pick aspects of and make such idle remarks.
What is lazy and disingenuous about Peter Todd's comments is that they don't address any of the real priorities identified by the various competing projects in the cryptocurrency space. Rather they are the remarks of an overgrown schoolboy trainspotting programmer who could care less about what he's implementing and everything about the tools he uses to implement it.
I'm not saying that's necessarily what he is, but I am saying that that is what such remarks characterize.
I have tried to address those things in this thread - ie present some level of business (or monetary) process analysis that is abscent from all the technological mud slinging. I've supported my arguments with a whole lot more background than Peter Todd did so I don't feel the need to defend petty point scoring factoids about perceived weaknesses in network security.
This debate is about something much more fundamental.
