If they had run some simple simulations with a few weeks of data, this would be crystal clear for everyone. The EIP is going to create incentives that favor the bid bot economy.

• There should be a factor of about 3x in total influence needed to get a post or comment past dust level, incentifying more medium sized accounts to use bid bots.
• The ROI for bid bot users will decrease while the ROI for bid bot owners will increase, incentifying a drop in price for bid bot usage.
• The drop in price for bid bot usage will free up money currently being pumped around, creating a demand for new stake delegated to bid bots.
• The flag pool will make self up voters (who hardly do harm to the content economy) more vulnerable to getting flagged, creating new insentive to delegate to bid bots.

I think there are a few simple fixes possible for this part:

• Drop dust level from 0.02 to 0.005
• Curator/Author buckets as described here

There are other issues with the EIP, that make it very likely to backfire even worse. The other type of backfire isn't that easy to simulate or measure after the fact though as it involves new accounts, platform growth and onboarding.

It is really interesting how Steemit believes it can grow its economy while not adressing inflation in any way and while not adressing the fact that STEEM is losing the battle for top content creators. For a real EIP we desperately need usefull features that burn STEEM and we need STEEM to truly compete with add revenue platforms and pull in those top content creators and their follower base from other platforms.

The EIP is going to backfire in more ways than one. The bid bot economy growth clearly being the most predictable and visible. Lets hope that lacking proper simulations (they wouldn't have gone through with the EIP in its current form if they had actually simulated the effects on the bid bot economy), they at least set evaluation parameters for success and failure for the EIP, so we can look forward to a HF22 in a few months that either reverts or fixes the current EIP implementation.
