After the legal limbo came a whole bunch of fractious disputes within and between multiple core teams -- initially FreeBSD (concentrating on PC-derived platforms) and NetBSD (cross-platform), both having some roots in the earlier, troubled 386BSD project led by Bill Jolitz, with some later forks from each group (most notably OpenBSD). Those persisted long after the legal issues were effectively settled, and really hindered the BSDs in general from keeping up with Linux-based OS distributions.
