I agree and disagree. The whale's "content choices" on things like SteemSports are decentralized. Maybe not decentralized to the point of all 100K+ accounts (mostly shill/scam accounts anyway), but there are probably a few dozen to a hundred or so whale accounts (of various sizes of course) and they choose what they want to vote for and support as do all the dolphins, mid-staked, and minnow accounts.

When you have a list of a dozen or so whales supporting SteemSports (at the moment; these things can change quickly in both directions), which in turn leads (along with votes from other non-whales) to SteemSports receiving and distributing a large portion of the reward pool, it is because we are each exercising our decentralized voting rights and expressing our preferences about what we think adds value.

If SteemSports posts were a ghost town and no one was participating in the games and benefiting from the wide and low-barrier distribution of rewards, the brand wasn't growing and developing new formats and content and investing in trying to grow the platform and its own brand, then I would stop supporting it. Other whales may or may not feel the same way.
