Subjectively you may personally think that it _must_ have a license somewhere, sure. But the file itself says right there--no copyright, no legal notice.

The rest is also your interpretation, and the reason I say that is that you're also kind of putting yourself in the objective audience's seat in creating the interpretation. So there's still a subjective hand-wave effect.

Get into the position of somebody who has no idea what the expectations are for "never taking more than you give"--where exactly is that line supposed to be, speaking in terms of details that matter...? ...and see if you can understand what it's like to be spoken to from someone else's set of simply-expressed, vague expectations connected to exactly which ethical framework we do not really know.

If you're "average joe"ing this, that's more of a subjective demonstration of where this kind of language may feel awesome for the author or even average-yourself-speaking-about-you-personally, but for others--what about them?
