I mean, honestly? Because the smaller users aren't offering me any value. Not saying they don't have value, they just don't offer me any value. There's no reason for me to upvote people for the sole reason that they're smaller users. If I think their comments or posts are informative/funny/etc., sure. But haejin brings me a lot of value, which is why I upvote a lot of his posts.
If other people find value in other users and want to upvote them, awesome. No one against berniesanders is against his ability to upvote people. They're upset about the flagging/downvote attacks against haejin and anyone else who stands up for haejin or criticizes berniesanders, many of which aren't whales and are much "lower" on the totem pole. Just today I saw speakyourmind downvote someone into oblivion on haejin's post for doing just that and then repeatedly taunt him by saying that he/she could do this all day "this is just one of my accounts." That kinda of bullying is what people are upset about.
Honestly, at this point I'm not sure what your argument is about. You started off arguing about haejin taking too many votes, then talking about how people should attack rancho instead, and then now you're asking why I don't support people upvoting. Those goalposts have moved mighty far from where we started.
I'm not asking you to upvote anybody. I'm asking why you don't support people downvoting Haejin to counteract a vote that they don't agree with.
The small users may be part of the reason you are aware of haejin, because they are responsible for his success...and that's all great. Before Rancho, steemit would be happy to consider haejin a success story. There were never any calls to downvoted him before. If he had the same earnings from different accounts, its doubtful that anybody would've said anything. Even if they had, they wouldn't be able to garner much support for it.
