OSS pre-dates GNU, sure. But has any other license had the same impact as GPL? Has any other set of OSS tools enabled so much as the GNU command line tools which were (and are) the foundation of Linux? I put him up for the night once. I'm a BSD guy, ran the local FreeBSD society. He was pleasant enough about BSD we could hang out a bit. I know what my preferences are, but I'm not so arrogant as to believe I'm anywhere near in a majority, and his influence through his work (including GNU), is completely obvious. Without him, we'd all be paying Microsoft, Sun, IBM or HP through the nose for licenses to much worse technology than we have today.
