The pools control the hash power plain and simple they are far more centralized. EOS will have 21 supernodes which can be voted out very quickly if need be. DPOS has proven itself with steem and bitshares but people want to keep repeating the same bs its fine with me time will show which of us are correct.
dpos is not proven yet. because the problem of "permanent nobility"(a rich become richer) has no solution so far and Steemit has already faced with that - 250 token holders control everything there, they promote their own posts and downvote any other
btw, even eth POS will have the same issue
