Freedom 0
每次出现类似最近MT授权变更的事件,就会激发我们对于自由软件乃至软件的思考。
Movable Type has never been Free Software, as defined by the Free Software Foundation. It has never been open source software, as defined by the Open Source Initiative. Six Apart survived and thrived in the blogging community because Movable Type was free enough.
文章的标题来源于FSF对于自由软件中“自由”二字的理解:
- The freedom to run the program, for any purpose (freedom 0).
- The freedom to study how the program works, and adapt it to your needs (freedom 1). Access to the source code is a precondition for this.
- The freedom to redistribute copies so you can help your neighbor (freedom 2).
- The freedom to improve the program, and release your improvements to the public, so that the whole community benefits (freedom 3). Access to the source code is a precondition for this.
