EOS is POS too, where some exchanges (Bitfinex was one of them) have already abused their voting rights. Ethereum will be a similar toy because of how most of the coins are held by centralized exchanges. People just like POS for its staking aspect, while everything else of negative nature is discarded because that's not of interest to them. 
this is why ethereum has delayed so much on POS, and is backtracking towards a hybrid POW-POS system. it's a much harder problem to solve than vlad zamfir and the others working on casper had imagined, especially when considering the economic/political forces around a complete removal of POW incentives. that's got contentious fork written all over it, even with the backing of vitalik. it's potentially a much worse version of the ethereum classic fork because miners are strongly incentivized to back the POW fork.
thankfully, they aren't as reckless as some bitcoiners make them out to be. they obviously don't want that. hybrid POW-POS at least retains mining incentives. as an added bonus for traders and investors, the hybrid POS incentives create massive pump potential. just look at DASH's historical chart.
