The FSF's statement on Windows 10

BOSTON, Massachusetts, USA -- Thursday, July 30, 2015 -- 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.
