i think you ar ethe who is misleading.. those developer have an extensive research about those exchange as well where their token can be listed! do you think these developers want their tokens to be listed in a crappy exchange?
That is actually true, those developers have their own knowledge on what exchange is good enough to list their coin. Aside from that, CMC is not the only website that they can use to find a good exchange, I am sure they know some sort of websites that can help them to find a good exchange.
