Looks like the mentioned Dash in that article is about the following (rather popular) app for MacOS

Appearently that app got removed because it was linked to another account that got involved with review rating tempering.
Apple then removed that specific Dash app.

This is unrelated to our own Dash app that we tried to get into the Apple store but could explain why Apple is overly cautious about Dash apps getting registered in their app store.
