They're going to get ~40% more of the remaining rewards they don't already extract before it increases the value of Steem. Almost all rewards now go to whales, with creators splitting less than 10%. Double curation rewards, and create a modified exponential rewards curve, then add a tax on rewards on creators, and, oh, hey, let's give flaggots free downvotes too.
The downvote pool doesn't acknowledge that what keeps most folks from flagging isn't VP cost. It's retaliation. Small stakeholders can be crushed by flaggots, and i've seen it happen more than once. Bernie will get more flags for free though.
None of that addresses the fact that investors are encouraged by potential capital gains, and with almost all the rewards being extracted by whales before the value can increase the price of Steem, there is no reasonable basis to expect capital gains. Hedge funds aren't in the business of self voting, or delegating to bidbots for their returns. They seek capital gains, and Steem can't give them any as configured, and EIP is making that worse.
And how do you imagine they will be getting 40% more? These principles already take into account maximizing behaviors. Unless you tell me the top X whales all agree to indiscriminately downvote everyone else, which I highly doubt. If you are a whale, and are just playing maximization, your incentive is to downvote other highly valued posts, presumably made by another whale, rather than small fish.
