People usually misunderstanding what decentralization means, thinking on equality.
Most of us, already know that inequalithy is human intrinsic.
The Decred's governance model, put the decision makers under a "skin in the game" set.
This model ain't better, but a different way from bitcoin.
Bitcoin has a tough governance, almost immutable via hardforks when it needs, always creating another coins instead of solving or improving the technical rules.
It could be perfect over decades as SOV, but as a softfork's hostage, some basic implements could be impossible to make, becoming it outdated.
Decred allows HF without creating another chains.
About centralization, new coins tend to be more centralized than old ones.
Greetings.
Right the governance models between BTC and DCR are almost complete opposites. Some say it is a strength of BTC to be almost immutable, but some day a fork may be necessary, and allow DCR to jump near or ahead of BTC. We will see what happens. I own both.
