Re: Ethereum is Now the Most Secure Public Blockchain, Overtaking Bitcoin
Nobody can quickly add a few changes as it suites them and I doubt if the same can be said about Ethereum. 
I think more people would regard that a bonus than they're willing to admit. It's cool to say you love decentralisation until it starts to impact on you, then you'll fall into the arms of the nearest smooth talker who'll slide your panties off and centralise you before you can hit your rape alarm.
Decentralisation is an inconvenience, commitment and long game that eventually pays off in spades when you sit back and think about it. Most people aren't strategic or disciplined enough to realise that.
I think the great thing about true decentralization is that it implies immutability. But immutability also means that the design is what it is, and no evolution can happen. As such, if the initial design has serious flaws, the system locks them in as long as it is truly decentralized.
One could even say that as no system that cannot evolve, will remain competitive, decentralized systems are doomed to centralize or to disappear, competed away by more advanced versions.
My own opinion of a true crypto currency is that it is what it is when the white paper is laid down, and will then live its life without changing a iota to that white paper, until it gets outdated, and dies. Anything of which the rules can be modified, is by definition centralized because a central entity could decide upon the modification, and could get the collusion of a majority over it.
