Against DRM 2.0 is a free copyleft license for artworks. It is the first free content license that contains a clause about related rights and a clause against digital rights management (DRM).
The first clause authorizes the licensee to exercise related rights, while the second clause prevents the use of DRM. If the licensor uses DRM, the license is not applicable to the work; if the licensee uses DRM, license is automatically void.
According to Internet Archive, the first version of the Against DRM 2.0 license was published in 2006. [1]

The Open Software License (OSL) is a software license created by Lawrence Rosen. The Open Source Initiative (OSI) has certified it as an open-source license, but the Debian project judged version 1.1 to be incompatible with the DFSG. The OSL is a copyleft license, with a termination clause triggered by filing a lawsuit alleging patent infringement.
A Creative Commons (CC) license is one of several public copyright licenses that enable the free distribution of an otherwise copyrighted "work". A CC license is used when an author wants to give other people the right to share, use, and build upon a work that the author has created. CC provides an author flexibility and protects the people who use or redistribute an author's work from concerns of copyright infringement as long as they abide by the conditions that are specified in the license by which the author distributes the work.
FairPlay is a family of digital rights management (DRM) technologies developed by Apple Inc. for protecting videos, books and apps and historically for music.
The Mozilla Public License (MPL) is a free and open-source weak copyleft license for most Mozilla Foundation software such as Firefox and Thunderbird. The MPL is developed and maintained by Mozilla, which seeks to balance the concerns of both open-source and proprietary developers. It is distinguished from others as a middle ground between the permissive software BSD-style licenses and the GNU General Public License. As such, it allows the integration of MPL-licensed code into proprietary codebases, as long as the MPL-licensed components remain accessible under the terms of the MPL.
Windows Media DRM or WMDRM, is a digital rights management service for the Windows Media platform. It is designed to provide delivery of audio or video content over an IP network to a PC or other playback device in such a way that the distributor can control how that content is used.
Extended Copy Protection (XCP) is a software package developed by the British company First 4 Internet and sold as a copy protection or digital rights management (DRM) scheme for Compact Discs. It was used on some CDs distributed by Sony BMG and sparked the 2005 Sony BMG CD copy protection scandal; in that context it is also known as the Sony rootkit.
Loi DADVSI is the abbreviation of the French Loi relative au droit d’auteur et aux droits voisins dans la société de l’information. It is a bill reforming French copyright law, mostly in order to implement the 2001 Information Society Directive, which in turn implements a 1996 WIPO treaty.
Tivoization is the practice of designing hardware that incorporates software under the terms of a copyleft software license like the GNU General Public License, but uses hardware restrictions or digital rights management (DRM) to prevent users from running modified versions of the software on that hardware. Richard Stallman of the Free Software Foundation (FSF) coined the term in reference to TiVo's use of GNU GPL licensed software on the TiVo brand digital video recorders (DVR), which actively block modified software by design. Stallman believes this practice denies users some of the freedom that the GNU GPL was designed to protect. The FSF refers to tivoized hardware as "proprietary tyrants".
This comparison only covers software licenses which have a linked Wikipedia article for details and which are approved by at least one of the following expert groups: the Free Software Foundation, the Open Source Initiative, the Debian Project and the Fedora Project. For a list of licenses not specifically intended for software, see List of free-content licences.
Defective by Design (DBD) is a grassroots anti-digital rights management (DRM) initiative by the Free Software Foundation (FSF) and CivicActions. Launched in 2006, DBD believes that DRM makes technology deliberately defective, negatively affects digital freedoms, and is "a threat to innovation in media, the privacy of readers, and freedom for computer users." The initiative regularly campaigns against the use of DRM by the media industry and software industry to increase awareness of the anti-DRM movement and pressure industries into no longer using DRM. They are known for their use of hazmat suits in their demonstrations.
A free-software license is a notice that grants the recipient of a piece of software extensive rights to modify and redistribute that software. These actions are usually prohibited by copyright law, but the rights-holder of a piece of software can remove these restrictions by accompanying the software with a software license which grants the recipient these rights. Software using such a license is free software as conferred by the copyright holder. Free-software licenses are applied to software in source code and also binary object-code form, as the copyright law recognizes both forms.
BSD licenses are a family of permissive free software licenses, imposing minimal restrictions on the use and distribution of covered software. This is in contrast to copyleft licenses, which have share-alike requirements. The original BSD license was used for its namesake, the Berkeley Software Distribution (BSD), a Unix-like operating system. The original version has since been revised, and its descendants are referred to as modified BSD licenses.
Proprietary software is software that grants its creator, publisher, or other rightsholder or rightsholder partner a legal monopoly by modern copyright and intellectual property law to exclude the recipient from freely sharing the software or modifying it, and—in some cases, as is the case with some patent-encumbered and EULA-bound software—from making use of the software on their own, thereby restricting their freedoms.
Digital rights management (DRM) is the management of legal access to digital content. Various tools or technological protection measures (TPM), such as access control technologies, can restrict the use of proprietary hardware and copyrighted works. DRM technologies govern the use, modification and distribution of copyrighted works and of systems that enforce these policies within devices. DRM technologies include licensing agreements and encryption.
The GNU General Public Licenses are a series of widely used free software licenses, or copyleft licenses, that guarantee end users the freedoms to run, study, share, or modify the software. The GPL was the first copyleft license available for general use. It was originally written by Richard Stallman, the founder of the Free Software Foundation (FSF), for the GNU Project. The license grants the recipients of a computer program the rights of the Free Software Definition. The licenses in the GPL series are all copyleft licenses, which means that any derivative work must be distributed under the same or equivalent license terms. It is more restrictive than the Lesser General Public License, and even further distinct from the more widely used permissive software licenses such as BSD, MIT, and Apache.
The GNU Free Documentation License is a copyleft license for free documentation, designed by the Free Software Foundation (FSF) for the GNU Project. It is similar to the GNU General Public License, giving readers the rights to copy, redistribute, and modify a work and requires all copies and derivatives to be available under the same license. Copies may also be sold commercially, but, if produced in larger quantities, the original document or source code must be made available to the work's recipient.
The Free Software Foundation (FSF) is a 501(c)(3) non-profit organization founded by Richard Stallman on October 4, 1985. The organisation supports the free software movement, with the organization's preference for software being distributed under copyleft terms, such as with its own GNU General Public License. The FSF was incorporated in Boston where it is also based.
GOG.com is a digital distribution platform for video games and films. It is operated by GOG sp. z o.o., a wholly owned subsidiary of CD Projekt based in Warsaw, Poland. GOG.com delivers DRM-free video games through its digital platform for Microsoft Windows, macOS and Linux.
Encrypted Media Extensions (EME) is a W3C specification for providing a communication channel between web browsers and the Content Decryption Module (CDM) software which implements digital rights management (DRM). This allows the use of HTML video to play back DRM-wrapped content such as streaming video services without the use of heavy third-party media plugins like Adobe Flash or Microsoft Silverlight. The use of a third-party key management system may be required, depending on whether the publisher chooses to scramble the keys.
