The voting power in the Hive SBI accounts is specifically earmarked to support the crowdsourced basic income. In effect, each HIVE submitted dedicates permanent support for the sponsored account, and the curation is provided back to the sponsor in the form of upvotes for their own support.
Any manual curation from the accounts would divert value, violate promises made to the community, and be an example of the forms of corruption that your video mentioned users should be watchful of. It would be like if hive.vote used its posting authorities to divert user upvotes whenever it encounters posts about itself. That would very obviously be theft!
We reblogged your post, and that can attract more voters with discretionary voting power, but our own VP is committed to delivery according to the promises made to our stakeholders.
