Bidbots are not what people vote on, they only vote on what they are paid to vote, so there is no opinion being expressed, just purely counting the payment (also known as a bribe).

No one personally benefits from the votes made here. The only gain to be had is seeing the results contribute to the success of Steem, which, ultimately, benefits content posters too. The number one contributing factor in lower rewards to authors is the decline in the price of Steem. Working or improve every aspect of Steem is in the interest of everyone, authors included.

You can disagree with the opinion of voters that this is a good use of reward funds, but it is still an opinion. Downvote if you like; that's the mechanism we have to disagree about rewards.
