What is the difference between an “aggregate” and other kinds of “modified versions”? An “aggregate” consists of a number of separate programs, distributed together on the same CD-ROM or other media. The GPL permits you to create and distribute an aggregate, even when the licenses of the other software are non-free or GPL-incompatible. The only condition is that you cannot release the aggregate under a license that prohibits users from exercising rights that each program's individual license would grant them. |

This is a legal question, which ultimately judges will decide. |

4. Conveying Verbatim Copies. You may convey verbatim copies of the Program's source code as you receive it, in any medium, provided that you conspicuously and appropriately publish on each copy an appropriate copyright notice; keep intact all notices stating that this License and any non-permissive terms added in accord with section 7 apply to the code; keep intact all notices of the absence of any warranty; and give all recipients a copy of this License along with the Program. You may charge any price or no price for each copy that you convey, and you may offer support or warranty protection for a fee. |

6. Conveying Non-Source Forms. [...] b) Convey the object code in, or embodied in, a physical product (including a physical distribution medium), accompanied by a written offer, valid for at least three years and valid for as long as you offer spare parts or customer support for that product model, to give anyone who possesses the object code either (1) a copy of the Corresponding Source for all the software in the product that is covered by this License, on a durable physical medium customarily used for software interchange, for a price no more than your reasonable cost of physically performing this conveying of source, or (2) access to copy the Corresponding Source from a network server at no charge. # c) Convey individual copies of the object code with a copy of the written offer to provide the Corresponding Source. This alternative is allowed only occasionally and noncommercially, and only if you received the object code with such an offer, in accord with subsection 6b. |

52. Most commenters on the subject supported the inclusion of both composite video/audio and RF outputs in the converter box. THAT Corporation (THAT Corp.) noted in its comments that “[t]o utilize these (composite video) outputs, consumers must be able to connect three separate cables from these converter box outputs to three corresponding inputs on the TV monitor. . . such a hookup requires a degree of technical competence lacking in many consumers.”[ 96 ]... |

How does GPLv3 make BitTorrent distribution easier? Because GPLv2 was written before peer-to-peer distribution of software was common, it is difficult to meet its requirements when you share code this way. The best way to make sure you are in compliance when distributing GPLv2 object code on BitTorrent would be to include all the corresponding source in the same torrent, which is prohibitively expensive. GPLv3 addresses this problem in two ways. First, people who download this torrent and send the data to others as part of that process are not required to do anything. That's because section 9 says “Ancillary propagation of a covered work occurring solely as a consequence of using peer-to-peer transmission to receive a copy likewise does not require acceptance [of the license].” Second, section 6(e) of GPLv3 is designed to give distributors—people who initially seed torrents—a clear and straightforward way to provide the source, by telling recipients where it is available on a public network server. This ensures that everyone who wants to get the source can do so, and it's almost no hassle for the distributor. |
