FSF launches campaign against Windows 7 and proprietary software Windows 7 Sins: The case against Microsoft and proprietary software The new version of Microsoft's Windows operating system, Windows 7, has the same problem that Vista, XP, and all previous versions have had -- it's proprietary software. Users are not permitted to share or modify the Windows software, or examine how it works inside. The fact that Windows 7 is proprietary means that Microsoft asserts legal control over its users through a combination of copyrights, contracts, and patents. Microsoft uses this power to abuse computer users. At windows7sins.org, the Free Software Foundation lists seven examples of abuse committed by Microsoft.

Important notice regarding impending lack of privacy, freedom and security from Microsoft Corporation.
