Yes, in the US at least copyright is specifically about reproduction/distribution, not use. This goes to the core of things every HNer encounters like open source licenses vs EULAs for example. A copyright license only governs somebody's ability to legally make copies and reproduce/derive/distribute in turn, not to what use they put it to for themselves. Absent any other contractual agreement they're perfectly free to mark up/modify/cut up a book or painting or the like that they have acquired, and they can sell that specific copy too. But other then the exceptions of Fair Use they can't distribute that work or derivatives without a separate license. Granted, most proprietary software slaps on additional restrictions which sadly have been found legal despite the massive perversion of contract and society it has entailed, but that's not inherent.
