The basis of your argument, that users want these developers to support another platform, does not make sense, because GrapheneOS does not require apps add explicit support for it. GrapheneOS has 99% android app compatibility.

The issue is not that this application isnt tested on GOS, its that an anticompetitive, illegal tool is being used to ban non-certified OSs when these apps would work perfectly otherwise.
