I agree with your article. I think that this example doesn't quite illustrate it:

Before you install Linux, do you think "What's the positive consequence of installing Linux?" or does it just seem like the sort of thing a free-software-supporter would do?

The first few times I did this, it was the second motivation. After a while, it became the first, namely that I got a system I had better control over, incorporating high-quality software. However, the first motivation was very good for the second. Without (lots of) people doing the sort of thing a free-software supporter would do, most of the good software I use out of work would not be available to me.

Your sentence has a strong/weak dichotomy whereas I think either motivation is acceptable.
