Right, but that's not an especially incitefull distinction to make. I imagine there are very few programmers around who love programming because it means they get to type lots of characters into a text editor in the same way that nobody enjoys sex because it means they get to exercise their hips.

In fact this is probably a big motivator in the number of open source libraries available now, they were developed by somebody who wanted to achieve thing X but they needed to create byproduct Y in order to do that.

So it makes sense to share by byproduct Y with the people who need to make thing Z.
