So which part of all those ecosystems are you claiming Europe could not maintain? Before you answer remember that Ubuntu is European, SUSE and openSUSE are European, Manjaro is European, most Arch developers are European, LibreOffice is European, KDE is European, GPG is European… I could go on, but, with all that shared expertise, are you sure that Europe does not possess the know-how to recreate and maintain all and every part of the Linux ecosystem?
Edit: When I say “European” I mean “started in and mainly run by people based in Europe”.
Excuse me… How is KRDC related to a release of digiKam? I am confused.
