Linux copies Unix (Bell labs), postgresql copied sql (IBM); redis is open core and is a bit of a different situation; newer examples are godot copying unity and blender copying other 3d programs. Each implementation is often better than the original, but they are not examples of novel inventions. I forget the history of gcc but assume it was not the only c compiler? Anki is based on supermemo, etc. Emacs was a novel invention, as was the concept of foss development. I love foss but it’s often more about freedom and trust and community and improvement, more than about innovation.
