If you are leaving, that's your decision ultimately. We will be sad about it, but we will also respect it.I am pretty unhappy about the situation and I am considering to pull all my apps from the Play store, close all related XDA threads and going back to anonymity.
The apps won't be sold in any case because in almost all cases this will not beneficial for the users of the app. There are plenty of examples of this.
However, I'd appreciate it, if you left the GitHub repo and this XDA thread available. So that anyone who wants to can fork the app and then inform the core users here in this thread. Even if it's just about keeping the libraries up to date and nothing else.
