Apple obligingly allows you to browse and download the open source software they use in OS X. Since they have listings for each version of OS X, I decided to take a look at how much software they were using that was only available under the GNU public license. The results are illuminating: 10.5: 47 GPL-licensed packages. 10.6: 44 GPL-licensed packages. 10.7: 29 GPL-licensed packages. 10.8: 22 GPL-licensed packages. 10.9: 19 GPL-licensed packages.
There has been a lot of GPLv3 discussion on tech sites. Perhaps predictably, a lot of it has missed the point or miscategorized the changes. If you read the history of the Free Software Foundation and the GNU Public License, you discover that it all came about because Richard Stallman found himself having to use broken software that he wasn’t allowed to fix. The entire purpose of the GPL is to ensure that everyone who uses a piece of GPL-licensed software can change that software, use the changed version, and distribute it to other people.
Red Pill 1.4 is out. It’s now Open Source under the GPL, so you can download the source code and hack away.
