I highlighted in my post how the changes pretty much require downvoting to be effective according to the lead engineer's comments. If people can just extract as much of the rewards pool as they want without any way to counter that, things will get far worse very quickly. You do see that, right? I'm not saying downvotes won't be abused (they will). I am saying less wealth extraction at the expense of others creating valuable content can be avoided if people use proof of brain and both upvote and downvote. If it is left out of this fork, then there will not be a way to effectively counter what is already a problem.
