Linux ate proprietary Unix, not Windows. Windows "servers" domination as listed by garner and others were tiny office NT4 domains back then, not internet facing websites and such. The web never really got dominated by MS and Unix and Linux always strangled MS in the cradle. Even stats by netcraft are misleading. Sure you'll see a lot of small business IIS crap and Exchange OWA, but that's no the web in general. The web has always been dominated by linux/Unix.
