I disagree. Everybody knows economics is broken, and partly a reason that drives people away. I think it is the most important issue that deserves dev resources and attention.
Giving 50/50 at least gives a fair chance to encourage use of organic voting and attarct more power ups.
This may divert some votes to authors for free rather than selling.
If you have noticed as soon as you power up bidbots send you memos with advertising their services and trying to get you use your sp for selling votes.
If you compare 25% return to almost 100%, which would you choose? 50/50 at least improves odds in favor of organic voting.
I don't expect 50/50 to work but I'm in favor of trying things out. However we don't really 'try something out' when we hard fork, we end up committing to that change because changing back would be another hard fork and a whole bunch of work just to get us back where we were.
We need some kind of trial period with a rollback at the end. That way we only continue with the new economics if we specifically elect to.
It is just so difficult to get everybody agree on something, especially the high stakeholders.
