2002 was before the tipping point, IMO. Open-source software existed, but wasn't always taken seriously. Linux was still widely perceived as being a hobbyist OS unsuitable for "real" applications. A lot of the Internet still ran on Windows and commercial UNIX servers.
By 2002 I was at Arbor Networks, shipping security software to tier-1 ISPs, and if we'd shipped it on a commercial Unix (let alone Windows) people would have looked at us like we had 2 heads. The writing was on the wall by end of the first dot com boom.
In 2003 I was somewhere south of Fort Worth, TX, having visited Dinosaur World, and shortly after leaving we stopped at a cafe that had three computers out which you could use. I looked at them while waiting for the coffee and they just seemed off, strange. It wasn't OS 9 nor X, it wasn't Windows... What was it? As I went over to look it hit me - holy cow, those are running that linux thing I've heard about! Their desktops were beautiful, totally different than the others. I knew then I wanted that.
Yeah, but the whole point was about GNU, and not so much UNIX culture, which was been free since the early days, given that AT&T could only charge a symbolic price for the tapes.
