A person can only "ninja mine" if they have insider information.. which means they would have to work for steemit inc etc. The term you are looking for is "early miners" and they took a chance on steem and it worked out for some.. not sure how that can be used against them now. Many do quite a lot for this place. This constant need to blame high stake holders is really quite silly and not beneficial.
We have an opportunity to make a difference with this foundation. Maybe you could give some feedback on the proposals and encourage others to do the same. We can make any changes if we don't actually try, this is a chance for the community to make the changes that they have been vocally saying need to happen.
