Hello - thanks for the feedback!
I have not investigated the activity of the individual members who support / work the project, but if they are not cashing out every dime they have made that is a very good thing indeed - it shows they are here for the long-run and that is all we can ask anyone to do .. remain invested in our common future.
There are many minnows who are not gaining anything from curation, and are not getting any traction for their posts - perhaps due to language barriers or the quality is just not there yet .. but they remain active and excited to be here because @steemsports provides - they see constant growth in their SP holdings and happily remain active as a result. The challenge to anyone who does not agree with what they are doing is to create something that achieves this for the minnows, without creating whatever issues they are worried about.
I entirely agree .. if there was more time spent bringing in new users, especially those who will purchase and powerup substantial amounts of STEEM, then such concerns would quickly evaporate I think.
