The mercy of few witnesses is probably why Jack wouldn't consider it (there may also be account scaling issues and then some probably) and instead is now investing in a research project.

But the beauty of open source is that anyone can fork the code, even create a new genesis block, and adapt the code to their desires before launching the platform.

Additionally, governance is flexible. As we have seen with bidbots. Stake is a weakness but stake (I mean money) also centralizes even Bitcoin. Only few, very few, specific mining pool operators are needed to collude and Bitcoin's rules can change over night.

Interestingly enough, because of the "stupid inflation" Steem/Hive is one of the healthiest DPOS models when it comes to collusion resilience. On EOS only the block producers grow. And they grow constantly, weakening collusion resistance every further day.

Here we still have 65% "organic" distribution, as well as interest. Eventually the stake will be more distributed.
