First, let me proclaim by bias: I'm a Free software fanatic. I do not ever want to run software that I can't read and, if I want to, modify. I just won't do it.
Open Source doesn't make sense to me and never has, becasuse you have always been able to give away your code.
The entire point of Free software is to avoid or even prevent closed proprietary software. That's why the GPL is "viral", eh? That's the whole point. Free software started when RMS wanted to fix his printer and Xerox said, "No."
Now we have companies like John Deere that use computers to lock out their own customers from fixing their own tractors. We have car companies charging to unlock heated seats and extra acceleration. Printers that lie to you about how much ink they have left, and brick themselves if you try to use cheaper unofficial ink. Etc.
You can be in charge of your computer, or you can be a peasant in someone else's fief.
