Idk. The devs run a business and still advertise with bean. If it is really abandoned instead of just low prioritized or idling they would start a coverup...in the end reputation sells.
The “likely” in the heading needs to be emphasized as we cannot say with certainty what will happen…
I would also not recommend anybody to subscribe or renew until there was a sign of life.
I am quite relaxed: 35 bucks for a lifetime update of an App is still quite cheap and I spent more for worse 😅
That they allegedly sold 1.000+ licenses without communicating their downfall is what lead me to involve Apple Support for a complaint.
