It's true, as having a good support that will ensure that the price won't dump too much then it will be fine.
However, listing on dex can be done even without the knowledge of the team, more likely they'll be surprise that their token was being traded on dex like forkdelta and ED. What the team should do is to avoid listing on exchange sites that have many bots as it will surely kill the price. Really, I had seen those.
