It wasn't dead dead but patches were not being upstreamed (as we say now), and so on. I do agree with you that even two variants were 1 too many. But even one would probably not have mattered as the AT&T lawsuit was a huge cloud on *BSD's popularity. As well as there were other factors. Linus and Linux had a much better story, its development was more nimble, with many younger and much more enthusiastic developers/users etc. Not that anyone really cares at this point except some graybeards! The Open SIMH project sounds great!
