Ah, so there is! [1][2[3]] I didn’t notice that. Thank you for pointing out that inconsistency in my previous comment; what I stated was conjecture, and, lo and behold, it turned out to be wrong.
Threema Libre is available exclusively via F-Droid. It requires a Threema Shop license, and the F-Droid app needs to be installed on your Android device.
In the same vein, a privately owned service, to me, is rather suspect if it is free of cost — the money’s gotta come from somewhere.
Threema sells to businesses. It’s a one time fee for personal.
