Good news, friends! A generous benefactor has offered to cover the costs of operating the game for at least a year and probably much longer, so subterfuge lives on!
In terms of App Store / Google Play availability, the iOS app is back on the App Store, but it's not on Google Play because it doesn't meets Google's latest requirements. As we mentioned previously, existing Android players can always re-download the app even though it's no longer listed.
We may have more news about this in the coming year, so stay tuned and happy subterfuge-ing!
