Hacktivism (a portmanteau of hack and activism) is the use of computers and computer networks as a means of protest to promote political ends. The term was first coined in 1996 by a member of the Cult of the Dead Cow hacker collective named Omega. If hacking as "illegally breaking into computers" is assumed, then hacktivism could be defined as "the use of legal and/or illegal digital tools in pursuit of political ends". These tools include web site defacements, redirects, denial-of-service attacks, information theft, web site parodies, virtual sit-ins, typosquatting and virtual sabotage. If hacking as "clever computer usage/programming" is assumed, then hacktivism could be understood as the writing of code to promote political ideology: promoting expressive politics, free speech, human rights, and information ethics through software development. Acts of hacktivism are carried out in the belief that proper use of code will be able to produce similar results to those produced by regular activism or civil disobedience.

Peter Ludlow (January 16, 1957), who also writes under the name Urizenus Sklar, is a professor of philosophy at Northwestern University. Before moving to Northwestern, Ludlow taught at University of Toronto, the University of Michigan, and the State University of New York at Stony Brook. He has done much interdisciplinary work on the interface of linguistics and philosophy—in particular on the philosophical foundations of Noam Chomsky's theory of generative linguistics and on the foundations of the theory of meaning in linguistic semantics. He has worked on the application of analytic philosophy of language to topics in epistemology, metaphysics, and logic, among other areas.

Ludlow has also established a research program outside of philosophy and linguistics. Here, his research areas include conceptual issues in cyberspace, particularly questions about cyber-rights and the emergence of laws and governance structures in and for virtual communities. MTV.com has described Ludlow as one of the 10 most influential video game players of all time, in part due to his role in showing how video game companies can be challenged as part of the gameplay. In recent years Ludlow has written nonacademic essays on hacktivist culture and related phenomena such as Wikileaks.

Cory Efram Doctorow (/ˈkɒri ˈdɒktəroʊ/; born July 17, 1971) is a Canadian-Britishblogger, journalist, and science fiction author who serves as co-editor of the weblog Boing Boing. He is an activist in favour of liberalising copyright laws and a proponent of the Creative Commons organization, using some of their licences for his books. Some common themes of his work include digital rights management, file sharing, and "post-scarcity" economics.

Born in Toronto, Ontario, Canada to Trotskyist teachers, Doctorow was raised in a Jewish activist household. His father was born in a refugee camp in Azerbaijan and Doctorow became involved with nuclear disarmament activism and as a Greenpeace campaigner as a child. He received his high school diploma from SEED School, an anarchistic "free school" in Toronto, and attended four universities without attaining a degree.

He later served on the board of directors for the Grindstone Island Co-operative in Big Rideau Lake in Ontario.

During 1992 Doctorow went on a volunteer visit to Costa Rica with Youth Challenge International (YCI), which he found "profoundly good and profoundly enriching".

Aaron Swartz (born November 8, 1986) is an American programmer, writer, political organizer and Internet activist. He is best known in programming circles for co-authoring the RSS 1.0 specification. He received mainstream media attention after his federal indictment and arrest on 19 July 2011, for allegedly harvesting academic journal articles from JSTOR.

Swartz is the co-founder of Demand Progress and the Progressive Change Campaign Committee. He currently lives in Brooklyn, New York.

Swartz was active in discussions of Internet standards from an early age, and co-authored the specification for RSS by the time he was 14.^{[citation needed]} Since then he has been a member of the W3C's RDF Core Working Group, co-designed the formatting language Markdown with John Gruber, and worked on many other projects.

Swartz attended Stanford University for a year, leaving to start the software company Infogami, a startup that was funded by Y Combinator's first Summer Founders Program. Infogami was built around a wiki backend, a subject of interest for Swartz since his early effort to develop theinfo, a wiki-based encyclopedia, in 2000.

Richard Matthew Stallman (born 16 March 1953), often shortened to rms, is an American software freedom activist and computer programmer. In September 1983, he launched the GNU Project to create a free Unix-like operating system, and he has been the project's lead architect and organizer. With the launch of the GNU Project, he initiated the free software movement; in October 1985 he founded the Free Software Foundation.

Stallman pioneered the concept of copyleft, and he is the main author of several copyleft licenses including the GNU General Public License, the most widely used free software license. Since the mid-1990s, Stallman has spent most of his time advocating for free software, as well as campaigning against software patents, digital rights management, and what he sees as excessive extension of copyright laws. Stallman has also developed a number of pieces of widely used software, including the original Emacs, the GNU Compiler Collection, the GNU Debugger, and various tools in the GNU coreutils. He co-founded the League for Programming Freedom in 1989.
