This document discusses software as property and whether copying proprietary software is wrong. It outlines the history of intellectual property rights, including John Locke's labor theory of property which argues people have a right to what they produce. While software challenges traditional notions of property, most countries consider copying proprietary software without a license to be illegal, though fair use exceptions exist for purposes like criticism, teaching, and research. The act of copying alone may not be wrong philosophically, but using the copied software deprives authors of payment for their labor.
