I think there is value to having programmers working on Ripple, but once it's done it's mostly done. That's not worth 20% of the entire economy (what they keep ). They should have done a combo of mining + non mining - 50% is mined , 40% given away 10% kept
Users have universally rejected pre-mining, regardless of the proportion. The goal is to eliminate the need for a centralized component such as XRP, not change its payout structure.
