The Document Foundation (TDF) is advocating for users to transition from Windows 10 to Linux, emphasizing its benefits as a free and open operating system. The deadline for Windows 10 support is October 14, 2025. TDF argues that users are not required to upgrade to Windows 11, which has new hardware requirements that may make many existing PCs obsolete. TDF promotes Linux and LibreOffice as a privacy-centric alternative that allows users to maintain their current hardware while accessing a suite of applications. Other Linux advocates, including KDE, have criticized Microsoft for its subscription model. Transitioning to Linux may be challenging for less tech-savvy users due to the learning curve and potential software compatibility issues. TDF suggests testing Linux on secondary partitions, but acknowledges that this may be difficult for some users.
