Apparently this is a very laudable initiative to fund OSI-approved
or FSF Free/Libre license based projects. This obviously applies to
GNUstep even more than to to GNOME due to its added cross-platform
advantage.
In my humble opinion, the only thing that still hinders GNUstep from
fully thriving is the lack of developer time to properly polish both
the underlying framework and the associated software relying on it.
It would thus be great if the Sovereign Tech Fund would be a viable
option to finance dedicated developers to allow for full time
focussing on GNUstep completion and polishing.
