Or maybe you want me to convince them they should pay someone else to do that because Stallman was right.
I'm sure some people are lucky enough to have friends and family who would accept your values instantly, learn the setup easily and be glad to pay someone else to do it. I can only speak from my own experiences and they don't reflect that (and as much as I might make a comment here and there I won't ever again try to push "my values" down someone's else throat).
Do you handle all of their Windows-related technical issues?
Are they incapable of learning to do it themselves?
Really?
Are you absolutely sure?
It's all-too-common for people to become dependent on technically-minded friends/family like us, but the fact is that it really isn't difficult for them to do it themselves.
The main barriers they face are:
1. I haven't done this before.
2. I don't immediately see the benefit.
What it comes down to is self-reliance. We can teach people to rely on themselves instead of rely on us.
As the saying goes:
> Build a man a fire, and he'll be warm for the night. Set a man on fire, and he'll be warm for the rest of his life.
... something like that, anyway.
For thinkers, problems are an opportunity to learn. Others, they don't see it that way, they want things to just work without making them think. If anyone you're trying to "teach" and "show them the way" ever loses money or have any kind of non trivial issue because "your linug broke my microsoft access" you'll be forever the guy that broke his computer. And he'll hate Linux forever.
