Abstract
In this paper, free and open source software are discussed. Open source is an intellectual property destroyer. Nothing could be worse than this for the software business and the intellectual-property business. Microsoft has an official open source presence on the Web (
www.microsoft.com/opensource), and in July 2010, Jean Paoli, the General Manager for Interoperability Strategy at Microsoft, delivered a keynote address at the O'Reilly Open Source Convention.
