Abstract

This paper describes the impact of different open source copyright licensing arrangements on competition in microcomputer operating system markets. We compare the historical evolution of the licensing policies of Microsoft Windows, Apple OS X and GNU/Linux operating systems. We argue that open source and free software licensing has been one of the most important factors of change in the microcomputer operating system markets in the recent years. We have seen new entrants in the relatively closed markets as well as renewed business models by incumbents. However, there has been no single open source strategy; all market players have adopted open source into their operating system strategy in one form or other.
