Creative Commons *is* a copyright license.
This is how you copyright a work: write it. Done!
Now no one can distribute it without your permission (except as allowed by fair use). You can give them permission to use it in certain ways using a new or pre-existing license, like CC (or GPL). There is no "conflict" between copyright and creative commons; quite the contrary, CC depends on (C). The GPL does too, as RMS has pointed out more than a few times.
Compare the size of the market to the size of the market for various other systems. There were 17 million Commodore 64 machines sold. I suspect there are easily this many people with open source desktops in the world; there are around 10 million users of Ubuntu alone. Does the author mean to say that the Commodore 64 was unsuccessful, was itself dead on the desktop, for having a mere 17 million users? It seems unlikely.
Being the sole desktop option is a hazardous place to be. If you believe in capitalism, you should prefer a mix, you should prefer that users (at some level, potentially corporate) decide which system to use.
I use GNU/Linux: Ubuntu on the desktop, Debian on servers and sufficiently high-end embedded systems. That's not about to change. I'm glad others are concerned about converting people, but only so far as it causes them to make better the software I use.
Fuck you, OP, and everyone who uses mod-point-martyrdom, to express their point of view.
"I have karma to burn" "I'll probably get modded down for this but..." "Ok, flame away"
Just make your point, and leave that crap out next time.
You'll probably get modded down for that....
What do I care if Linux works for you?
I run Linux for me; it works for me. I may encourage you to run it too, but it's not my problem if it doesn't work out. Remember the bit about "no warranty"?
Now, if you're paying for a working system or support, that's a different story. If you get a Linux shop to build you a PVR, they'd better give you a working machine. But demanding that volunteers fix your problem is insane.
The only one responsible for making your computer work is you.
Mathematics generally requires TeX. For example, the AMS. (They prefer various forms of TeX, but will also accept submissions on paper, so you could use MS-Word. But it's a world of pain for all involved.)
I couldn't dream of using anything else, even outside of math, if only to get proper kerning and small-caps.
