You're absolutely right! Now, I hope many doubters will close their mouths, because they will have no arguments left. Although I believe that this is not an indicator that the coin is a scam. And the listing of the project is also happening, just at a slower pace than users expected.
As long as it's still running it's okay to be a little slow as long as it's still a great deal of certainty, and when a project is still viable as it is, it's not worth calling it a scam, even if the person doesn't like it personally.
