Watching interviews of Richard Stallman always makes me terribly sad.
People laugh at him and they just don't understand his point at all.
They can't even imagine a person writing a program WITHOUT the
intention of making as much money as possible with it. People don't
even begin to think about "free or proprietary". They get stuck at the
point where someone says: "Free software doesn't cost you any money!"
That's it. That's where they stop thinking. Their brain literally
shuts down. Anything beyond this point is so bizarre to them that they
can't do anything else than laugh.
You can't blame them for it. Exploring new concepts is hard and takes
a lot of effort. It's a lot easier to stick what you already know. And
that's what makes me sad.
