Does Patreon require the ability for users to remove someone's funding when you dislike them? No, you vote with your dollars by funding who you like and that is the extent to your power. Downvotes are in no way a requirement for the system, that is a religious stance some are taking here. It is foolishness because #NewSteem is less populated, less valuable and has more disgruntled people ditching it than old Steem because the bot votes didn't go away, they just switched to the downvote control tool.

Upvotes are a way of supporting financially those that you believe are worthy of it and it is proportional to your investment, that is as far as it needs to go. No, we do not need to control how others vote, including self-votes. Why? Because your votes are personal decisions that do have an impact on the overall value of the network, but only proportional to your risk. So, people acting foolish with their votes is fine because the damage is limited to the amount of money they have sunk into the network.

Having downvote control is similar to a neighborhood organization that starts giving home owners rules. True freedom loving people despise this sort of domination over people, forcing people to do with their own property what the organization wants and not what the owner wants. That's not decentralized freedom, that's more tyrannical governance.
