There are a lot of them, they don't want to delegate it and don't want to upvote anybody. It makes me angry as well to see so many people getting voting power 100% without using it. Some of them even are well upvoted by others and dapps, but still not using it. Sometimes I think that there is something hidden that we don't know about, some reason that so powerful people are not upvoting others, or rarely using their power.
