The World Wide Web is not the Internet.

As I was writing it out, I knew someone was going to complain.

It's an abridged timeline. Brevity because the point is the date, not the fine detail.

But since I don't care to argue on the internet... edited.

"we have been open-source long before it was fashionable"

An abridged timeline:

1960s to 1980s: hobbyist and academic/research computing create thriving public domain software ecosystems (literally the birth of FOSS)

1983: The GNU Project begins

1989: The World Wide Web is created

1991: Linus Torvalds posts the first Linux kernel to USENET

1992: 386BSD is released; Slackware is created

1993: NetBSD is forked; Debian is created

1994: FreeBSD 2 is released

1995: Red Hat is created

[a decade of FOSS and the internet changing computing and research forever]

2005: A collection of low-cost microcontroller education tools, benefiting from half a century of FOSS, is formalized into something called "Arduino"
