<h2>Your Freedom Needs Free Software</h2>
(追記) <address class="byline">by Richard Stallman</address>
<div class="introduction"> (追記ここまで)
<p>Many of us know that governments can threaten the human rights of
software users through censorship and surveillance of the Internet.
Many do not realize that the software they run on their home or work
computers can be an even worse threat. Thinking of software as
(削除) ‘just (削除ここまで)
(追記) “just (追記ここまで) a (削除) tool’, (削除ここまで) (追記) tool,” (追記ここまで) they suppose that it obeys them, when in
fact it often obeys others instead.</p>
(追記) </div> (追記ここまで)
<p>The software running in most computers is <a
(削除) href="/philosophy/categories.html#ProprietarySoftware">non-free, (削除ここまで)
(追記) href="/philosophy/categories.html#ProprietarySoftware">nonfree, (追記ここまで)
proprietary software</a>: controlled by software companies, not
by its users. Users can't check what these programs do, nor
prevent them from doing what they don't want. Most people accept
this because they have seen no other way, but it is simply wrong
to give developers power over the users' computer.</p>
<p>This unjust power, as usual, tempts its wielders to further
misdeeds. If a computer talks to a network, and you don't control the
software in it, it can easily spy on you. Microsoft Windows spies on
users; for instance, it reports what words a user searches for in her
own files, and what other programs are installed. RealPlayer spies
too; it reports what the user plays. Cell phones are full of (削除) non-free (削除ここまで) (追記) nonfree (追記ここまで)
software, which spies. Cell phones send out localizing signals even
when (削除) ‘off’, (削除ここまで) (追記) “off,” (追記ここまで) many can send out your precise GPS location
whether you wish or not, and some models can be switched on remotely
as listening devices. Users can't fix these malicious features
because they don't have control.</p>
<p>Some proprietary software is (追記) <a href="/proprietary/proprietary.html"> (追記ここまで)
designed to restrict and attack its
(削除) users. (削除ここまで) (追記) users</a>. (追記ここまで)
<a (削除) href="http://badvista.org/">Windows (削除ここまで) (追記) href="https://badvista.fsf.org/">Windows (追記ここまで) Vista</a> (削除) is (削除ここまで) (追記) was (追記ここまで) a big
advance in this field; the reason it (削除) requires (削除ここまで) (追記) required (追記ここまで) replacement of old
hardware is that the new models (削除) are (削除ここまで) (追記) were (追記ここまで) designed to support unbreakable
restrictions. Microsoft thus (削除) requires (削除ここまで) (追記) required (追記ここまで) users to pay for shiny new
shackles. (削除) It is (削除ここまで) (追記) Vista was (追記ここまで) also designed to permit forced updating by corporate
authority. Hence the <a (削除) href="http://badvista.org/">BadVista.org</a> (削除ここまで) (追記) href="https://badvista.fsf.org/">Bad Vista</a> (追記ここまで)
campaign, which (削除) urges (削除ここまで) (追記) urged (追記ここまで) Windows users not to (削除) ‘upgrade’ (削除ここまで) (追記) “upgrade” (追記ここまで) to
Vista. (削除) (For the equally malicious Windows 7 and (削除ここまで) (追記) For later (追記ここまで) Windows (削除) 8, (削除ここまで) (追記) versions, which are <a
href="/proprietary/malware-microsoft.html">even more malicious</a>, (追記ここまで) we
now have <a (削除) href="http://windows7sins.org/">Windows7Sins.org</a> and
<a href="http://upgradefromwindows8.org/">UpgradeFromWindows8.org</a>.)
Mac OS (削除ここまで) (追記) href="https://www.fsf.org/windows">Upgrade from Windows</a>.
Mac OS (追記ここまで) also contains features designed to (削除) restrict (削除ここまで) (追記) <a
href="/proprietary/malware-apple.html">restrict (追記ここまで) its (削除) users.</p>
<p>Microsoft has (削除ここまで) (追記) users</a>.</p>
<p>In 1999, Microsoft (追記ここまで) installed back doors for the US government's (削除) use in (削除ここまで) (追記) use.
Researchers <a
href="https://www.techworm.net/2013/06/nsa-built-back-door-in-microsofts-all.html">
disagree on what those back doors can 
do</a>, but Microsoft has made that question less important by its forced 
software installation, which is even worse. If (追記ここまで) the (削除) past (<a
href="http://www.heise.de/tp/artikel/5/5263/1.html">reported (削除ここまで) (追記) 1999 code won't let 
NSA spy (追記ここまで) on
(削除) heise.de</a>). We cannot check whether they have successors today. (削除ここまで) (追記) you, Microsoft can force another change which will do so. (追記ここまで) 
Other proprietary programs may or may not have back doors, but since we 
cannot check them, we cannot trust them.</p>
<p>The only way to assure that your software is working for you is to
insist on (削除) Free/Libre (削除ここまで) (追記) free/libre (追記ここまで) software. This means users get the source code,
are free to study and change it, and are free to redistribute it with
or without changes. The <a href="/gnu/linux-and-gnu.html">GNU/Linux
system</a>, developed <a href="/gnu/gnu.html">specifically for users'
freedom</a>, includes office applications, multimedia, games, and
everything you really need to run a computer.
See (削除) <a href="http://www.gnewsense.org/">gNewSense.org</a> for
a (削除ここまで) (追記) our list of (追記ここまで) <a href="/distros/distros.html">totally (削除) Free/Libre version (削除ここまで) (追記) free/libre
versions (追記ここまで) of GNU/Linux</a>.</p>
<p>A special problem occurs when activists for social change use
proprietary software, because its developers, who control it, may be
companies they wish to protest—or that work hand in glove with the
states whose policies they oppose. Control of our software by a
proprietary software company, whether it be Microsoft, Apple, Adobe or
Skype, means control of what we can say, and to whom. This threatens
our freedom in all areas of life.</p>
<p>There is also danger in using a company's server to do your word
processing or email—and not just if you are in China, as US lawyer
Michael Springmann discovered. In 2003, AOL not only handed over to
the police his confidential discussions with clients, it also made his
email and his address list disappear, and didn't admit this was
intentional until one of its staff made a slip. Springmann gave up on
getting his data back.</p>
<p>The US is not the only state that doesn't respect human rights, so
keep your data on your own computer, and your backups under your own
custody—and run your computer with (削除) Free/Libre (削除ここまで) (追記) free/libre (追記ここまで) software.</p>
