Why Hackers Use Linux ?

I often think why hackers are portrayed by media as mad peoples banging keyboard in-front of black terminal with green characters on it ...& most importantly they never show them with windows or similar OS.

So , I compiled following points :

1. The simple thing is hackers will never pay for anything ;) 
2. By using Linux Hackers have full ownership of all libraries & all the code which is important because many vendors like :Microsoft etc never open their code or libraries & API's thus limiting constraints on experimentation.
3. Its an open source OS
4. Most of the linux is built in modules so these modules are re-usable so hackers find it easy to use those modules according to their requirement
5. Linux OS built upon a large knowledge base & thousands of enthusiasts are there to help you if you're stuck on somewhere.

    6. Great control over everything he is doing .

By Term Hacker I mean:  Hacker is someone who likes to learn and explore the things in a new way & stuff like that.
