The rewards distribution mechanisms have been carefully calibrated to deliver ROI and over 90% of rewards to whales. This has not been done to kick people off the platform, but has been done preferentially to keeping new users on the platform.
Clearly, PoS delivers governance to the largest stakeholders, and they haven't been men of vision, but instead properly concerned with financial prudence and management of their stakes.
The one thing Justin Sun needs from us to be able to bring his marketing and onboarding competence to bear on Steem is raising retention to industry standards, and this necessitates reining in profiteering by whales such that new content creators are nominally encouraged to stay.
We continue to bleed highly valuable users today. We've managed to curb the incredibly blatant vote buying (Srsly, you could have knocked me over with a feather when EIP worked to do that) but we need to do more.
When we can retain ~50% of new users that come here, then Sun has good reason to undertake bringing us new users, because we won't just allow whales to mine their content for ROI, but will allow that good content to deliver them rewards that encourage them to stay and keep making it.
