I don't see anything obviously wrong in any of the Dash reviews (I think this is the correct app):

It also seems somewhat unlikely that a developer with such great reviews would deliberately trash his competitors.

I wonder if Apple's automated fraud detection system detected it as a false positive, simply because he got so many good reviews?

Turns out a relative of his who he paid account setup for, and shared some devices with, had the fraud.

Now Phil Schiller (by name) wants to force Kapeli to post a blog saying Apple was right in banning him: https://blog.kapeli.com/dash-and-apple-my-side-of-the-story/

I bitch about it here: https://plus.google.com/+NickRichards/posts/H7iuMTcYLSn essentially saying Apple is not bold ("courageous") enough to notify _him_ about the upcoming fraud ban, only the guilt-by-association Niece's account.

Who are Dash's competitors anyway?

None AFAIK. Google search, Visual Studio / Other IDE Intellisense features.
