Few Linux folks who know about RMS consider him a saint. It's just as unfortunate that the free (speech, beer, whatever) software movement has a whacko self-absorbed figurehead, as that the proprietary software movement has a whacko self-absorbed figurehead (that would be the legendary chair-throwing monkeyboy Ballmer).
I am grateful for the early work RMS did, in particular the gcc compiler, because that made possible a lot of technical work that I did in the 90's. For that matter, anyone who uses any of the modern BSD UNIXes, MacOS-X, and others, is indebted to RMS and the gcc developers.
However, RMS has become a religious nut-case, and like all religious nut-cases, he's lost touch with what it's really about. He cares now only for his own glorification. Witness how he's screwing GPLv3 into a corner.
Look, I work as Director of SysAdmin for a company that writes and sells proprietary software; I use and maintain servers running Windows, NetBSD, Solaris, Linux, and MacOS; and I love and hate them all because nothing is perfect. I support users running all of the above plus Vista. If I were a religious nut-case, I'd be out of a job.
I happen to be writing this on my home Linux box, but my WinXP box alongside is crunching on a task and my Mac Mini is downloading some updates. I use what works best for the task. Free software often (but not always) does it best.
So I don't think you're playing fair, to paint all GNU, much less all GNU/Linux or other free software boosters as leftists. Many of us are simply folks who don't think that Microsoft et al -- despite their overwhelming market success -- are doing the best job out there, and we'd like to try to do better ourselves. You're welcome to judge the results as inferior -- it's a free country. I prefer to have a mix, since that way I can do anything I need to do, on at least one of these boxes.
I don't, I just state simple facts like Stallman is a green party whacko and Torvalds came from a family of well known communists and sit back and watch those act like I criticized their family instead of admitting the obvious. They may not all be leftists but when they attack me for questioning those like Stallman who are, you certainly have to wonder.
