I think you are asking yourself the wrong questions. I did not state that no one other than bidbots are making profits. The question isn't about profits, but about the rate of distribution of STEEM across the network.

It should not take a degree in mathematics to understand that before bidbots, the STEEM was getting distributed across the network. After them, it is getting concentrated in the hands of a few users.

Yes, others may be making profits. But, profits do not safeguard this network from would be abusive tyrants unless we are making enough of them that the disparity between wealth starts to balance. But instead, we are all making the worst of us, the ones willing to hijack an entire network for their own selfish reason, the most poweful of us. By accepting bidbots and using them, we are electing and empowering oligarchs who have no regard for the community as a whole. Which is a stupid move for any community.
