The post explains the experiment clearly. I wanted confirmation and got it.

This is like an 'experiment' where you hold out an apple and drop it. Pretty obvious foregone conclusion. Did you do a control, e.g. release the same app on Homebrew with similar marketing? Release another app and market it? You have not explicitly stated what you were attempting to show- it seems to be your personal sentiment that MAS does your marketing for you without considering other possibilities.
