The value of the time of whales is better spent on their business than fine-tuning their rewards. All they have to do under this - or any tweak to rewards along these lines - is delegate to a bot and exert 0 effort to fine tune their profiteering to extract almost all of the rewards from the pool.
The bidbot owners take care of everything for them. All they have to do is sell their profits on the market, and continue to crash the price of Steem.
That's what will continue to happen, only it will happen faster with a modified exponential rewards curve, and doubling curation rewards. EIP is the last rush to extract the value left in Steem which there is presently a race to sell before the price crashes. Then the profiteers will move on to the next target.
That's what profiteers do.
