Read the threat again. Decentralized governance is coming. John is stating that decision making does not depend on it. He does not see value until the coin is at least $0.50. until then, decisions will be made via other models.
If you think decentralized governance is the most important thing, then certainly stay in Dash. IMO, it is not the most important thing though it is important. The reasons are as follows:
1) Coins without decentralized blockchain based governance have far less adoption and market cap than coins that do 2) The coin best known for it, Dash, has not really accomplished much with their decentralized governance. Considering decisions still come top-down (just look at this poll), it has the same effect.
The only benefit that may be seen is that Dash has a bounty program. Which is what the governance model has turned into. Core makes all the decisions, but masternodes pay people who have interesting projects in a bounty-type system.
This, to me, is not actually a benefit. As previously stated, the end result has been few people want to volunteer. Why volunteer my time if I can be paid for it? If people refuse to pay me, then I feel cheated as they pay others or I feel demotivated as they must not like my idea, etc. Hell, I see governance proposals that are using it like kickstarter "Hey, fund my startup because I am not even passionate enough to fund it myself".
So, decentralized governance while a great theory has not proven itself in practice.
