Agree. It's not art but an unfounded fear that one might steal/fork the source and get more credits.

I disagree that this is a likely reason. There's nothing novel about the implementation except the size of the source code.

If I wanted to do that I'd just not release any source. And--credits for what? Making a basic line texteditor? Those are a dime a dozen.
