What are you worried about? You don't seem to want to profit monitarily from your labors, but would like to get some recognition. Therefore, it seems to me:

1) If you create whole programs and somebody steals them...well, that would suck.
2) However, you are creating components, not whole programs. If somebody else includes them in a commercial app, THEY will make money, but they also added value.

So what is it you really want? Do you object to somebody mainge money off code that includes something you wrote, but for which you asked for no monetary compensation? Is the point of view, "I didn't write this for profit, but if somebody uses it for profit, then I want some of it.", or the view that, "I didn't write this for profit, and NOBODY should profit from its use.", or is it something else?
