Yes, the only reason I cared for Linux in first place was that the POSIX support wasn't that good.
I am convinced that if POSIX subsystem was UNIX serious, GNU/Linux would never taken off on PC, and the whole would be divided between SGI, HP-UX, Solaris, Aix and Windows NT.
The BSDs would be much bigger today if it wasn't for AT&T going after them hard in the early '90s, exactly when both them and Linux were starting to take up speed. I think that things could have gone way different if the BSDs were bigger and more popular, in quite unpredictable ways (it's not like they haven't been popular anyway though - see Darwin, or the Playstation OS for instance)
Actually Linux was very SysV like back in the day, so it was more like the stuffy OS's that people liked.
GCC was the real catalyst, With even SUN which had used bundled dev tools as a early selling point was unbundling them and charging more, many x86 UNIXes like SCO didn't even come with a tcp/ip stack without an extra fee...and you couldn't take C code from HP to another system and actually have it compile.
As Solaris is really just a sysV-ification of the bsdish sunOs...the introduction of posix as a least common denominator, and Linux being closer to the commercial-ish unixes it was just an easier sell for a lot of users.
In hindsight it may seem silly, but in may projects I was involved with, linux using sysV /etc/init.d/, vs BSD's /etc/rc.conf was the driving factor, because /etc/rc.conf was a shared dependency and harder for us to modularize projects.
IMHO the real Linux advantage is that it was using the gnu user land, and thus gcc worked well with it and companies started to sell commercial support early.
But there were still flavor wars from all sides all the time, and being an ex-op on #unix and #unixhelp from the 1990s, I dealt with them all.
But BSD and heck even ITS etc... was the free-for-all, anything-goes, platform of record.

IMHO what really differentiated Linux were
a. the bazaar development approach, which lowered barriers to contribution, felt more transparent and "safer" with regards to what was going on in kernel land
b. the GPL, which while annoying to certain companies due to its viral nature, it at least guaranteed that no competitor could just develop a major innovation, grab the kernel and all of your contributions and run with them, undercutting you in the process
and also a noteworthy mention was the fact the BSDs were basically sabotaged by AT&T via their nefarious set of lawsuits, which nipped in the bud any semblance of advantage they had
386BSD and its derivatives (eg FreeBSD) weren’t really attacked by SCO like other UNIXes were. In fact SCO filed more lawsuits against Linux than they did (for example) FreeBSD.
FreeBSD was also used heavily in the late 90s in ISPs and similar domains.
I think you are a possibly a decade off on the timing here.
USL v. BSDi is what impacted the BSD side, and it was during that lawsuit before Novell bought USL etc.... that the problems were that allowed Linux to make gains while the net/2 distros were in a waiting game IMHO.
The timing absolutely helped Linux and GNU being packaged as a complete system by the various distros etc..., and common OSS distribution points like Walnut Creek and PHT were very much concerned about USL v. BSDi and in an era when you had to make long distance phone calls to download with a modem, a lack of CDroms etc... absolutely caused a dip in adoption of the BSDs.
By the time the IBM v. SCO lawsuits happened (2003) the UNIX wars were long gone and Linux was already established.
SCO/Interactive/Coherent/etc... and other x86ish UNIXes were quite common in my work in the early 1990s, but the whole unix wars is way to complicated to cover in a single post.
The post .com bubble SCO lawsuits really just didn't matter much, the consolidation that happened in the early 90's that ended the UNIX wars, plus Intel killing most of the commercial unix independent CPUs with Itanium untruths and impossible promises and an inability for the major vendors to adapt to a lower margin model etc... killed those off.
The SCO lawsuits were really just the flailing of a dyeing company which was the end result of WordPerfect buying Novell with Novells money and local Utah politics.
Sorry, I don’t think my point was very clear. I wasn’t saying that SCO sued Linux in the 90s nor that the UNIX wars had zero impact.
Just that FreeBSD was still used a lot in the 90s and managed (at least from what I experienced) to dodge most of the concerns that companies had deploying other UNIXes.
I mean, it’s not like UNIX use dropped to zero overnight.
So you did see a lot of Internet companies using FreeBSD as their platform of choice. For a while, it really did look like FreeBSD was becoming the dominant server platform in that domain. Not everyone too Linux serious at that time. It wasn’t until at least 99 when Linux became a viable competitor to FreeBSD.
But once Linux did gain favour its popularity sky rocketed. Which is exactly why SCO took various Linux shops to court.
You’re sidestepping my point that FreeBSD was in widespread use in the 90s.
My point about SCO wasn’t clear though. I was just saying FreeBSD wasn’t as embroiled in the UNIX wars as the others, ie referencing SCO vs Linux to demonstrate how even Linux suffered more time in the courts than FreeBSD did.
