I’ll be honest: I feel conflicted about the framing of this as a European project.
Depends on what the 'European' is supposed to convey. Interpreted geographically, as in this para, yes, it is limiting. But Reboot, and I suppose Rebuild too, always used European as a label for a certain set of values. In the same way the EU is not geographically defined in terms of who can join or cannot. The Treaties say you have to embrace the values stated in the EU Treaties art 1A and 2 to be able to join.
