This is yet another flaw in the design of Steem. There’s no transaction fees to support the periphery nodes which serve up the content. If Dtube is instead taking 25% of the author’s rewards, that is a misaligned incentives because this is supposed to be a decentralized system, not another set of overlords taking share of profits. Transaction fees for serving content should be paid by those receiving the content and should be very minuscule such that nobody cares! Or transaction fees can be minted from the money supply with each user having an allocation (proportional to their wallet balance) to spend for this purpose only.
This is yet another in a long list of egregious flaws in the design of Steem.
