Yeah, or maybe just stay centralized and capture the network and sell it for a profit.
Yup, history is littered with examples of that, with ZERO examples of the reverse.
Its not too big of a deal there will be a wide range of clients to choose from with varying levels of centralization. Market will decide what the best approach is at any given time. Early on better ux will win, but they are not mutually exclusive and both styles will likely converge overtime on both sides.
