29 To protect your rights, we need to prevent others from denying you 27 Developers that use our General Public Licenses protect your rights
30 these rights or asking you to surrender the rights. Therefore, you have 28 with two steps: (1) assert copyright on the software, and (2) offer
31 certain responsibilities if you distribute copies of the software, or if 29 you this License which gives you legal permission to copy, distribute

34 For example, if you distribute copies of such a program, whether 32 A secondary benefit of defending all users' freedom is that

38 know their rights. 36 encouraged by the resulting cooperation. However, in the case of
39 37 software used on network servers, this result may fail to come about.
40 Developers that use the GNU GPL protect your rights with two steps: 38 The GNU General Public License permits making a modified version and

43 41
44 For the developers' and authors' protection, the GPL clearly explains 42 The GNU Affero General Public License is designed specifically to
45 that there is no warranty for this free software. For both users' and 43 ensure that, in such cases, the modified source code becomes available

58 stand ready to extend this provision to those domains in future versions
59 of the GPL, as needed to protect the freedom of users.

61 Finally, every program is threatened constantly by software patents.
62 States should not allow patents to restrict development and use of
63 software on general-purpose computers, but in those that do, we wish to
64 avoid the special danger that patents applied to a free program could
65 make it effectively proprietary. To prevent this, the GPL assures that
66 patents cannot be used to render the program non-free.
