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. It does not matter if you can't read code: whether or not it is available directly affects any user.

No one can look inside

Windows comes without its source code. More than that: all users must abide to the license term that says:

You may not reverse engineer, decompile, or disassemble the software.

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!"

Richard Stallman, Why Software Should Be Free

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.

Lähtekood on retsept tarkvarale. Kuidas saab üks parandada sööki liiga palju soolaga, kui keelatud vaadata retsepti järgi, mida süüakse?

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

Mida te pigem usaldate: paketti, mida on keelatud õppida või paketti koos retseptiga?
