​I​'ve thought and written a bit about this question a bit [
and I'll not repeat all of here but 
​as one of the people that did switch from 386BSD to linux at the time, the reason for me was purely because of the AT&T/BSDi case.    You are right, I wanted a "free" (i.e. very inexpensive) UNIX for the 386 and the "big guns"​ were not going to give it.   I thought we had it the 386 port BSD which I had helped in a small way to create.   

​But I like, most hackers of the day, misunderstood incorrectly​ the case to be about trade secret and the all based around the 1956 consent decree, IBM vs AT&T; telephones and the computers. I was worried AT&T would win because it was going to hard to cleaim that that the BSD code was not a derivative work of the AT&T copyright code base (not understanding the trade secret  and the  copyright difference mattered).

So...I switched to Linux not because I thought it was "better" - in fact, I b*tched (and still do) about many gratuitous differences, but as I knew that we needed something for "consumer" HW (which was bring driven by the WINTEL economics), and I was willing to use the "lessor" technology (Linux) because it was "good enough" and gave me what I needed (UNIX on a PC/386).  I thought (incorrectly) somehow original Linux's European authorship was going to protect me and my fellow hackers ever though it was not as good as my beloved BSD system.

Simple put - using Christiansen's theories:  Linux "won" because:
  • it was "good enough",
  • had a lot of people behind it that valued that was there and invested in making it "better", and
  • the economics of the platform (PC/386 - WINTEL etc) was on the fastest grow curve [and its Christiansen's economic disruption was displacing the Mini & Workstation].

BTW: at the time, I argued with the Roger Gourd and the OSF folks, that if they released (sold) the OSF/1 RI uK which had not AT&T technology in it (again thinking Copyright not Trade Secret); I was suggesting $100/copy there was a market for it.  I just could not get them interested.

Sun has done the RoadRunner and had their 386 port of Solaris; but again.  All the "UNIX" folks were still interested in pushing out "iron" so were blind to the WINTEL economic disruption.

Woulda, Coulda, Shoulda .... sigh
