GNU General Public License

GPLGNU GPLGPLv2
The first version of the Affero General Public License (AGPLv1), was published by Affero, Inc. in March 2002, and based on the GNU General Public License, version 2 (GPLv2).
These problems included tivoization (the inclusion of GPL-licensed software in hardware that refuses to run modified versions of its software), compatibility issues similar to those of the Affero General Public License—and patent deals between Microsoft and distributors of free and open-source software, which some viewed as an attempt to use patents as a weapon against the free software community.

The second version (AGPLv2) was published in November 2007, as a transitional license to allow an upgrade path from AGPLv1 to the GNU Affero General Public License (a variant of the original Affero GPL license that is compatible with GPLv3).
The GNU Affero General Public License is a free, copyleft license published by the Free Software Foundation in November 2007, and based on the GNU General Public License, version 3 and the Affero General Public License.

Copyleft

copyleft licenseweak copyleftSoftware hoarding
Both versions of the Affero GPL were designed to close a perceived application service provider (ASP) loophole in the ordinary GPL, where, by using but not distributing the software, the copyleft provisions are not triggered.
For projects which will be run over a network, a variation of the GPL is provided in the Affero General Public License, which ensures that the source code is available to users of network software.

Quine (computing)

quinequinesself-reproducing program
Around late February 2002, Kuhn suggested, based on the idea of a quine (a program that prints its own source code), that GPLv2 be supplemented with a section 2(d) that would require derivative works to maintain a "download source" feature that would provide complete and corresponding source code.
The "download source" requirement of the Affero General Public License is based on the idea of a quine.

At that time, Poole contacted Bradley M. Kuhn and Eben Moglen of the Free Software Foundation to get advice on a new license that would close the ASP loophole in GPLv2. In the Free Software Foundation's judgment, the added requirement in section 2(d) of Affero GPL v1 made it incompatible with the otherwise nearly identical GPLv2.
