Free Software
Free software is the principle that the people who use a program should be free to run, study, change, and share it — freedom as in liberty, not as in price. It is usually treated as a developers’ ethic, but the wiki treats it as something more load-bearing: the precondition that makes trustless cryptographic tools possible at all.
The four freedoms
The movement was launched by Richard Stallman, who founded the GNU project in 1983 and the Free Software Foundation in 1985 to build a complete operating system that users would be free to control. Its definition of free is a specific set of freedoms: to run the program for any purpose, to study how it works and change it (which requires access to the source code), to redistribute copies, and to distribute modified versions. Software that denies these — that ships only as an opaque binary the user may not inspect or alter — is, on this view, a means by which its author exercises power over its users. The claim is moral before it is technical: control over the software you depend on is a question of freedom.
Copyleft
Free software’s decisive invention is copyleft, embodied in the GNU General Public License (GPL). Ordinary copyright lets an author forbid copying and modification; copyleft uses that same legal power to guarantee the opposite. A copyleft licence grants everyone the four freedoms on one condition — that any derivative work be released under the same terms — so the freedom cannot be stripped out downstream by someone who takes the code, improves it, and closes it. It is copyright turned against itself, a licensing hack that propagates freedom virally through every fork. This is the counterpoint to the wiki’s treatment of intellectual property: where the libertarian IP debate asks whether ideas can be owned at all, copyleft is a pragmatic tool that works within copyright to enlarge the commons.
Free versus open source
A later, milder framing — open source — describes the same practice of shared, modifiable code but justifies it pragmatically (better software, faster development) rather than as a matter of user freedom. The code is often the same; the disagreement is over why it matters. For the wiki’s purposes the two converge on the property that counts: the source is available to be read and rebuilt by anyone.
The cypherpunk precondition
This is where free software stops being a programmers’ preference and becomes structural. A privacy tool, an encryption library, or a money protocol that you cannot inspect is one you must simply trust — trust that it has no backdoor, leaks no keys, and does what it claims. That is exactly the trust the cypherpunk program refuses: it is the software instance of trusted third parties as security holes. Open source converts that trust into verification: the code can be audited by anyone, compiled reproducibly, and checked against its claims. The Bitcoin maxim don’t trust, verify applies to the software as much as to the ledger. It is no accident that every load-bearing tool in the wiki’s cypherpunk canon — PGP, Tor, the public-key messaging stacks, Bitcoin, Monero — is free and open source. Auditability is the security model, and free software is what makes it available.
Place in This Wiki
Free software sits beneath the wiki’s cypherpunk and peer-to-peer threads as an enabling ethic rather than a headline. The movement’s insistence that users control their tools is the same commitment, in the domain of code, that the wiki makes about money and speech: that the systems people depend on should not be black boxes controlled by someone else. It is the software precondition for censorship resistance and for crypto anarchy.
