Z:gnu-www-ja-words-to-avoid--b370b4-The term =26ldquo;sell software=26/en

The term &ldquo;sell software&rdquo; is ambiguous. Strictly speaking, exchanging a copy of a free program for a sum of money is  selling the program, and there is nothing wrong with doing that. However, people usually associate the term &ldquo;selling software&rdquo; with proprietary restrictions on the subsequent use of the software. You can be clear, and prevent confusion, by saying either &ldquo;distributing copies of a program for a fee&rdquo; or &ldquo;imposing proprietary restrictions on the use of a program.&rdquo;
