I guess the word "decentralized" means nothing to you.
No, it means something for me but there is apparently difference in the meaning for you and me.
Keep in mind the cost parameters are quite different for a pure PoS block chain. There are little computation requirements, and thus negligible capital requirements. The notion of 'initial stakeholders' takes on quite a different meaning in this context. As long as the code is open source[1] then there is little barrier to entry, and disagreeable initial disbursements are not likely to be adopted(due to higher competition).
Long story short, at day one, the developers are the only ones who invested real-life efforts in this system, consequently they are the only ones interested in not destroying it.
More details about my point of view -

I see a
bitbucket project. But honestly I haven't fully examined this currency yet.
