There's an old joke about how 99% of lawyers give the rest a bad name. That, in very broad brushstrokes, is how I feel about the demographic of the computer user base out there. Now, I've left the computer industry, and I no longer do tech support for anyone but a very few of my very closest friends, so in a sense I suppose one could argue that, whatever the composition of computerdom out there, it doesn't have an opportunity to affect me any longer.
And I'd probably agree with that assertion, generally speaking, for the most part. However, much like in big business or politics or other similar fields of endeavor, what goes on and what is allowed to go on can and does affect us all. Most of the "really bad" stuff you have heard about going on that, fortunately, got stopped, was stopped in 11th hour actions by a few who were well-informed enough, opinionated enough and could rally enough force or momentum to their cause. A savvy and interested user base would likely not have allowed these things to have been potentially successful.
As blessed with brains and the capacity for individual initiative as we are, the sad truth is that most people out there (and again, this applies to many areas of endeavor) don't bother to do anything, or don't care, and so things like Net Neutrality, broadcast flags and (almost) root kits on music CDs get by us. These are things which I object to and refuse to go along with or participate in the usage thereof; and yes, for those who don't mind and/or don't care, in addition to all the other idioting that goes on ("Do I format my hard drive to get my Word file?", etc.) I hold a rather dim view of my fellow computer user.
There are plenty of savvy Windows users out there, and there are plenty of dumb Mac users out there. It's true, the hardware hardly makes the man (please forgive the mixed metaphor), but in my experience people buy Macs because they are savvy enough to know better (that is, that there's more to computers than just "Computers running Microsoft"), and people who buy Windows-based PCs do so because, well, it's what people buy (read: "Don't all computers use Microsoft?")
If anything, it may be arguable that the "truly savvy" out there run Linux, but that's another kettle of fish for another day.
Now, you can agree with me or not -- hey, it's a free country -- but that really isn't the point. You asked me to defend my position, and I have now done so.
