I think smooth was referring to DACs (the term apparently invented by Daniel Larimer), or the concept that the corporation would be somehow decentralized and yet still be a corporation. If you have voting, directors, etc, then it will still behave as (by definition) a top-down corporation and thus is not decentralized. You can't replace corporate governance with a block chain and still have a corporation.
It is decentralized enough to where the government can't easily or cheaply shut it down. In turn it can offer services that are highly regulated much more efficiently and cheaply than legacy corporations. DACs can reduce hosting costs by utilizing nodes of the network and users, and costs of employment by utilizing smart contracts.
Sure, it is "controlled" by large stakeholders and management which is elected by such, but that's just how corporations work. To say there is no benefit to "decentralizing" or using blockchain technology for corporations is silly.
