>MIT and source out on GitHub is the easiest way to build trust. You will find that some people simply "steal" your work in this arrangement, but much like with movie piracy I don't think they ever intended to compensate you or anyone else.

You've chosen the license which allows "stealing", why did you do that if you don't like that? Nobody forced you to do that, I hope.

How can I trust the person who published their code with the strict legal terms, but becomes sad when other people use their code exactly as the author said it could be used?

Every once in a while I read discussions about licenses, and puzzled every time why the author of the software chooses free license when the freedom of copying and distribution is seem to them as pirating. If the license is not suitable for you, why choose it?!

Licenses are about legal possibilities. You're looking for social/moral terms instead if I understood you correctly (something like CoC).
