The point was about who contributes the wast majority of the work nowdays. Also, before GNU there indeed wasn't much of a FLOSS community in the modern sense, it was much closer to colleagues sharing program tapes with their modifications as a courtesy. So sure, there were programmers sharing code between each other, but that was kind of informal sharing, more because nobody placed much value on software alone at the time and university labs didn't always wanted to start from scratch. In fact the reason RMS started GNU in the first place was precisely because he felt that kind of sharing culture was being eroded.
