The EIP was never about "fixing" the trending page. It was about changing the game theory mechanics of the reward pool distribution to counter:

• Low value spam posts.
• Self-vote "abuse" (bid bots are a variation of this).

The change in the reward curve counters "hidden" low value spam posts and comments by reducing the ROI.

The 50/50 makes it economically agnostic to earn via posting or curating. Since voting requires less effort than posting it essentially incentivizes the former as opposed to the latter. This reduces the incentive to self vote 10 posts per day.

The downvote pool eliminates some of the opportunity costs of downvoting so it makes it easier for stake holders to remove rewards from less "honest" forms of posting.

Of course a side effect was that some of the more obvious "bad actors" were less likely to leech from the system and not show up on the trending pages but that was not the main point of it.
