1 00:00:11,123 --> 00:00:15,141 Free software is the first battle 2 00:00:15,141 --> 00:00:18,162 in the liberation of cyberspace. 3 00:00:18,163 --> 00:00:20,223 Who controls your computer? 4 00:00:20,245 --> 00:00:25,678 Is it you or is it some big company that's really controlling it? 5 00:00:25,774 --> 00:00:27,786 What is a computer? 6 00:00:27,790 --> 00:00:31,858 A computer is a universal machine. 7 00:00:31,873 --> 00:00:35,125 It will do any computation you want it to 8 00:00:35,125 --> 00:00:37,405 because you give it a program that says 9 00:00:37,439 --> 00:00:40,167 what the computation is that you want. 10 00:00:40,179 --> 00:00:43,982 The computer only knows how to get out an instruction and do it, 11 00:00:43,998 --> 00:00:46,358 and get out another instruction and do it. 12 00:00:46,358 --> 00:00:50,557 The program has the instructions, it says what to do. 13 00:00:50,612 --> 00:00:55,252 By writing the right program, you can make it do anything. 14 00:00:55,252 --> 00:00:57,665 Well, almost anything. 15 00:00:57,670 --> 00:01:00,698 Who gives the instructions to your computer? 16 00:01:00,728 --> 00:01:04,327 You might think it's obeying your instructions 17 00:01:04,355 --> 00:01:07,495 when really it's obeying somebody else first, 18 00:01:07,552 --> 00:01:13,953 and you only as much as that company will let it listen to you. 19 00:01:13,992 --> 00:01:16,049 With software, there are two possibilities: 20 00:01:16,093 --> 00:01:21,491 Either the users control the program, or the program controls the users. 21 00:01:21,492 --> 00:01:23,842 It's inevitably one or the other. 22 00:01:23,893 --> 00:01:27,092 In order for the users to control the program, 23 00:01:27,133 --> 00:01:30,920 they need the four essential freedoms. 24 00:01:30,920 --> 00:01:34,404 That's the definition of free software. 25 00:01:34,435 --> 00:01:38,355 Free software respects the user's freedom and community. 26 00:01:38,367 --> 00:01:42,394 Now, we often call it "Libre" using the French or Spanish word. 27 00:01:42,408 --> 00:01:45,716 Pronounce it as you like, the point is that's what we mean. 28 00:01:45,734 --> 00:01:48,798 We don't mean it's gratis, we're not talking about price. 29 00:01:48,799 --> 00:01:51,038 We're concerned with your freedom, 30 00:01:51,045 --> 00:01:55,554 and we sometimes say "Free/Libre" to show that. 31 00:01:55,575 --> 00:01:58,476 Freedom zero is the freedom to run the program 32 00:01:58,500 --> 00:02:01,239 as you wish for whatever purpose. 33 00:02:01,239 --> 00:02:05,357 Freedom one is the freedom to study the source code of the program 34 00:02:05,377 --> 00:02:09,717 and change it, so it does the computing you want it to do. 35 00:02:09,738 --> 00:02:11,449 But what is the source code? 36 00:02:11,465 --> 00:02:14,576 Every program typically will have two forms. 37 00:02:14,639 --> 00:02:18,390 There's the form that you can read, and you can understand 38 00:02:18,406 --> 00:02:20,485 if you know the programming language. 39 00:02:20,527 --> 00:02:21,929 That's the source. 40 00:02:21,949 --> 00:02:24,321 That's what programmers write and change. 41 00:02:24,342 --> 00:02:27,222 Then, there's the executable, which is a bunch of numbers 42 00:02:27,222 --> 00:02:29,583 which even a programmer can't figure out. 43 00:02:29,602 --> 00:02:31,583 If all you get is the executable, 44 00:02:31,594 --> 00:02:34,982 it's a horrible pain in the neck to the figure out what it does, 45 00:02:34,995 --> 00:02:36,866 and even harder to change it. 46 00:02:36,879 --> 00:02:41,069 So, to give you the real possibility to study and change it, 47 00:02:41,069 --> 00:02:42,941 they've got to give you the source code. 48 00:02:42,958 --> 00:02:44,621 That's a requirement. 49 00:02:44,629 --> 00:02:47,453 With those two freedoms, 50 00:02:47,464 --> 00:02:50,301 each user separately can make a copy 51 00:02:50,321 --> 00:02:54,091 and start changing it and make it do what she wants. 52 00:02:54,105 --> 00:02:56,746 That's individual control. 53 00:02:56,754 --> 00:02:58,914 But what if you're not a programmer? 54 00:02:58,922 --> 00:03:01,703 You look at the source code, and you don't understand it. 55 00:03:01,743 --> 00:03:04,783 Individual control isn't enough. 56 00:03:04,795 --> 00:03:06,962 We also need collective control, 57 00:03:06,975 --> 00:03:10,363 which means any group of users are free to work together 58 00:03:10,373 --> 00:03:12,914 to adapt the program to what they want. 59 00:03:12,929 --> 00:03:16,026 Of course, in the group, some of them are programmers. 60 00:03:16,049 --> 00:03:18,721 They're the ones who actually write the changes, 61 00:03:18,722 --> 00:03:20,839 but they're doing it as part of the group 62 00:03:20,859 --> 00:03:22,608 for what the group wants. 63 00:03:22,622 --> 00:03:25,388 Of course, the group doesn't have to be everybody. 64 00:03:25,409 --> 00:03:27,586 Others can use it some other way. 65 00:03:27,587 --> 00:03:30,131 They're all free to do that. 66 00:03:30,141 --> 00:03:33,501 Collective control requires two more essential freedoms. 67 00:03:33,505 --> 00:03:36,976 Freedom two is the freedom to redistribute exact copies, 68 00:03:36,976 --> 00:03:38,927 to make the copies and then give them away 69 00:03:38,946 --> 00:03:41,026 or sell them when you wish. 70 00:03:41,059 --> 00:03:43,012 Freedom three is similar, 71 00:03:43,035 --> 00:03:45,276 but it's for your modified versions. 72 00:03:45,300 --> 00:03:49,172 You're free to make copies, and then give them or sell them when you wish. 73 00:03:49,240 --> 00:03:52,202 If you do have these freedoms, then it's free software, 74 00:03:52,216 --> 00:03:54,093 the users control the program. 75 00:03:54,130 --> 00:03:56,785 But if any of those freedoms is missing, 76 00:03:56,819 --> 00:03:59,537 then the users don't control the program. 77 00:03:59,538 --> 00:04:05,580 Instead, the program controls the users and the developer controls the program. 78 00:04:05,594 --> 00:04:10,632 So, that means this program is an instrument of unjust power 79 00:04:10,680 --> 00:04:14,539 for its developer over the users. 80 00:04:14,563 --> 00:04:17,500 That means the users don't have freedom, 81 00:04:17,560 --> 00:04:21,797 that's non‑free, proprietary software which we've got to get rid of. 82 00:04:21,826 --> 00:04:25,262 When you've got proprietary software, what happens?
