I absolutely disagree with this change to 'downvote' as my understanding from the Steemit inc post was that downvotes could be used to simply disagree with a post's content as opposed to it being used to flag breaches of guidelines or 'rules'.
Its all very well them saying its to provide balance to the reward pool but the power shift in the use of removing rewards will of course again favour large stakeholders who can then use the downvote as a valid tool for censoring.
Lets imagine you're an argumentative git who is of a strong opinion.....you'd be screwed!
I think its another nail in the coffin of free speech and along with Steemit forcing their choice of post onto my feed as 'featured'posts, its another step in the totally wrong direction.
