Open source software means security…
…of technology since it can be permanently audited by users and the community around the world. It can be analyzed and checked completely and without restriction.
…of investment since through the extensive rights granted by Free Software, the software is property of the user instead of being leased only through expiring licenses. Thus, open source is a real investment.
…of strategy since open source is subject to control by the user. This means users can freely make decisions about their future strategy.
