Not his job to get it listed on there but also not his job to think he is the nutts and make sure we can't get on there so yeah it is clearly that idiots fault.
He hasn't made sure of shit, Poloniex is going to list Waves if and when they're ready and a disagreement on an unrelated subject is not a reason any business person would refuse listing a stock that is essentially a public company.
There are plenty of coins worthy of being listed there and it is likely after New Year that Poloniex will do some house cleaning and remove a few and replace them with more promising coins such as Waves, but at the moment they probably feel, like Bittrex, that their platform as it is is already overbloated and in need of some attention.
Nobody owes you anything goy!
