I actually agree with the restoration of the 50/50 split (50% to the author and 50% to the curators). I wrote a post about it a long time ago that describes why I thought it was bad: https://steemit.com/steem/@blocktrades/voting-abuse-and-ineffective-curation-a-proposal-for-blockchain-level-change
One change did come out of that post: previously, for the first 30 minutes of voting, even more of the rewards went to the author. This made it super-advantageous to immediately self-vote on all your posts (and get bidbots to do the same) as all the rewards on votes just after the post was published went to the author.
Steemit reduced that period down to 15 minutes (instead of the 5 minutes I suggested) and nullified rewards for that period on a gradually decreasing basis (I had suggested they split the rewards during that period as if they had voted at the same time to discourage immediate voting just to be the "first" to curate the post in order to get more curation rewards).
