"when I started on Linux it [386BSD] wast available (although Bill Jolitz series on it in Dr. Dobbs Journal had started and were interesting), and when 386BSD finally came out, Linux was already in a state where it was so usable that I never really thought about switching. If 386BSD had been available when I started on Linux, Linux would probably never had happened."
Yes, I just replied to "it [the lawsuit] may have been a motivation for creating Linux in the first place".
As for why Linux "won"; I think the low bar to contributing in the earlier days helped a lot; BSD tended to be a lot more bureaucratic. And there was also some amount of drama and splits in the early 90s, which probably didn't help either.
