What about source code?

The source code details the way a program works (it is effectively what programmers write). Without it no one can understand how the software is built. Bạn không phải lo lắng nếu không đọc được mã nguồn: cho dù nó có sẵn để người ta đọc hay không thì cũng không ảnh hưởng trực tiếp đến bất kỳ người dùng nào cả.

Không ai có thể nhìn vào trong

Hệ điều hành Windows được phát hành mà không hề công bố mã nguồn. Còn hơn thế nữa là tất cả người dùng phải tuân theo những điều khoản mà giấy phép nêu ra:

Bạn không thể reverse engineer, decompile, hay disassemble phần mềm.

As such, it is illegal to work out how Windows or Microsoft Word are designed. It is even illegal to try. You are also forbidden to modify the program for any purpose.

This restriction in the license makes sure that Microsoft remain the sole organisation that understand how their products work. Windows is very much like a car that only the original manufacturer is allowed to service.


You might say, "How do I change this recipe to take out the salt?" and the great chef would respond, "How dare you insult my recipe, the child of my brain and my palate, by trying to tamper with it? You don't have the judgment to change my recipe and make it work right!"

You can trust free software

It comes as no surprise that proprietary software is severely lacking in terms of security, compared to software whose source code is freely available (including GNU/Linux).

Free software means programmers can change the code to repair flaws. It means you can hire someone to really check how secure your software is. It means you can benefit from the contributions of a world-wide community to improve safety and reliability. Fifteen million users run GNU/Linux without an anti-virus, in complete safety. And the servers behind search engines and banks run on it too.

Source code is the recipe for software. How could one improve on a meal with too much salt, if forbidden to look at the recipe used to cook it?

Using Windows and Office requires us to not ask nor search for the source of the software. Only Microsoft developers can modify your program.

Which would you rather trust: the package you are forbidden to study, or the package with the recipe?
