That is quite correct. When we removed Piezo from the Mac App Store a year ago, we didn't send out a press release, nor seek publicity over this move in any way. We simply removed it and explained why on our blog (https://weblog.rogueamoeba.com/2016/02/12/piezo-1-5-arrives-...). That was it.

We can certainly debate how well-established or tech-savvy our users are (though I will note that Piezo is by far our simplest application, and used by the least technically savvy among our user base). But to say that we did this in a “public fashion” is just false.
