"Why not, some said: "let him dump, we could buy cheap STEEM". Oh yeh? If that happens, price gets trashed, expect more whales (bad or otherwise) to gain more power."

So him having the stake is bad, but him dumping and allowing the community to buy it, cheap, is also bad. If he dumps on exchanges everyone has the same chance to buy it, whale or minnow. That seems like a strange justification for opposing a dump. I think the best thing that could happen for decentralization is a bunch of steem gets sold for dirt cheap. But that is just me.
