his witness vote just notified me about his existence and activity, I don't downvote others removing their votes or upvote those giving me a vote for that matter, I sometimes even downvote those who vote for me which may result in some unvoting and that's okay if they wanna use hive that way. Similar to how his tag here today notified me about his current activity. Assuming I have a vendetta against him cause of the unvote speaks against all my other actions on this chain which can easily be tracked as they are immutably stored. The reason for the downvotes has been rehashed too many times for me to again write down here, you can go look it up on his previous posts if you want to bother, that is if you're not him but someone else who's confused.
Most about what you said about cartel voting, rich getting richer, etc doesn't apply to hive on the same level as the other chains you mentioned and that's quite obvious if you took a look at what goes on there. I don't disagree that Steem and EOS are in trouble in that regard.
