Without whales the game wouldn't turn a profit, and it wouldn't exist. Without F2P players the whales have nobody to complete against with the advantage they paid for. Would you start playing a phone game if everyone that played had spent $20,000-50,000, and you would have to do the same just to be equal with them?
The game needs a thriving ecology of sea creatures of various sizes. We all need to get along. That doesn't preclude an occasional conversation about how even/uneven the playing field should be, or how much money is too much for a tiny fraction of the code/pixels available in the game though.
