I don't mind it in the sense that I know it will happen anyway. I object to my code being used in proprietary projects, though with small snippets it's not such a big problem for me.

But the problem is big enough for me to want to make sure the code is covered by a license I like. This is just how my priorities are to me.

Why would you answer a question if you then don't want the person to use the answer you give?

He's not saying that. He's saying that while he understands people will infringe his copyright, he still wants to help. He's not saying you can't use the answer, just that you need to use the answer under a license he chooses.
