there's no reason to act like that for the dev, instead if he's better than them he should put all the exchange, this is something for the community firstly. Then if the community think that coinexchange doesn't deserve to be used, well they won't, easy and simple. If the dev remove the coinexchange it'll be a disaster. In the most of the cases an exchanche can't be sure if a coin is legit or not, they only want to make money and they add everything can bring them btc. But it's only my opinion
