The article says "Well, SUSE knows what they are doing because they have been in the Linux business since 1992. Try to find a Linux “vendor” (or in that sense, distributor) which is older. You won’t. There aren’t any."
This is deceptive. SLS was the first linux distribution in 1992. Slackware was developed from that and released in 1993. The first SUSE distribution was a German translation of Slackware. Stating the obvious, Slackware is still around and is older. Then in 1996 Suse made their own distribution based on Jurix.
