> The freedom to study how the program works, and change it so it does your computing as you wish (freedom 1). Access to the source code is a precondition for this.
> In order for freedoms 1 and 3 (the freedom to make changes and the freedom to publish the changed versions) to be meaningful, you need to have access to the source code of the program. Therefore, accessibility of source code is a necessary condition for free software. Obfuscated “source code” is not real source code and does not count as source code.
IMO exactly the same logic applies to code history and bug trackers: you need access to those things to be able to study how the program works. A code dump is much the same thing as obfuscated source code: you can build the program from it, but you can't understand the program from it.
