"The Free Software Foundation urges everyone to reject Windows 10 and join us
in the world of free software. Like all proprietary software, Windows 10 puts
those that use it under the thumb of its owner. Free software like the
GNU/Linux operating system treats users as equals and gives them control over
their digital lives."
