Rejecting HF21 in its current state
Firstly, let me be clear that I'm a low ranked witness, and my opinion is largely irrelevant. Nevertheless, I'll do my duty as a witness and state my sincere opinion. If I reject a hardfork that everyone else accepts, it'll mean that I'll be kicked out of Steem and no longer be an active witness.
I support the general idea of the EIP, overall, but I do not think the current implementation proposals being chucked around are justified.
I have discussed the pros and cons of each proposal in the EIP, in general, here.
Addendum: Before commenting, please see my full thoughts in the comment linked above. This post is but a follow-up from there.
However, I'm yet to see any data, simulation, or evidence, to justify the dramatic changes, all rolled into one hardfork. The change to 50:50 is a 100% increase in curation rewards, a 33% pay cut to the content creators without whom there'll be no curation; giving abusive whales 10%-25% free downvotes is drastic etc. Remember, one abusive whale can effective now vindictively kill off hundreds good content creators at zero cost. There's a greater cost for minnows to unite and start a flag war with whales, whilst for whale it's pretty easy to set up a bot and just take a bunch of people they don't like down to $0 forever. Self-voters can simply set up a bot to revenge flag anyone who dares downvote - it'll always be minnows that'll be forced to retreat from a flag war. I'm also concerned about the convergent linear curve hampering the few genuine minnow content creators, but overall I'm in favour of it. Finally, SPS is going to be introduced without any funding committed by anyone. You can read my detailed thoughts in the comment linked above, and alternative brainstorming in my blog.
I was expecting better implementations of the EIP concepts, but these are simplistic and naiive. Have we learned nothing from the past?
To conclude, I remain in support of the general concepts of EIP, but disappointed by the facile implementations proposed thus far. I will, of course, change my opinion based on further tweaks to HF21, and I hope there'll be some.
PS: As some have correctly pointed out, there has been no official announcement about all of this being included in HF21. Nevertheless, my opinion on all of the above is contained here or linked elsewhere. I will, of course, reevaluate my opinion based on the final HF21 proposed by the developers.
PPS: In a follow-up post, I explain why moving to 50% curation rewards will not see any significant changes.
