Linux

What I know
I know that Linux is a free operating system, such as Windows or Mac OS. I also know that anyone can download it for free and that most computers can run on Linux as well as Windows (or even Mac OS) at the same time. This is done by choosing the system you would like when starting the computer. I think this is called multiplatform computers. I know that its symbol/identity is a penguin.

Questions
1. Is Linux better than Windows? than Mac OS?
2. How does Linux's CEO win financially if it is a free operating system?
3. Are there multiple viruses for computers running on Linux? (as it is for Windows) Or are these a tiny amount (like Mac OS)?
4. Why is Linux's symbol a penguin?

1. The Penguin is named Tux and it is the Linux symbol because Linus Torvalds was fond of penguins. He made a contest and then told the participants that he liked penguins.
2. Linux virus protection is better and cheaper than Windows'.
3. Linux Desktop manipulation is much more flexible and 'free' without barely any locks and restrictions. (like Windows)
4. Linux is much better than Windows 8 for gaming.
5. Linux is the only operating system of the above that is free.
6. Updates to Linux occur every 6 - 9 months, while Windows takes 5 years and Mac OS 2 years. Also, Linux's updates are free while both Windows and Mac charge for their updates.
7. In Linux, as in Mac OS, you can have multiple desktops, something that Windows does not let you.
8. Linux can run on any platform, from mobile devices to supercomputers. Mac and Windows cannot.
9. Linux is like Mac, malware is practically unheard of.
10. Linux, since it is free, primarily wins money from investments.
11. There are 863 known malware viruses for Linux.

CONCLUSION:
Windows sucks.
This connects to my life because now I have been convinced that Linux is not as lame as I thought. I have been so persuaded that I might even download it. Also, I now see that you can make money from free stuff (which might help spark something in the future). If I ever create something, I now have decided that I'll too create a contest and tell the contestants what I am fond of, whatever that might be at whichever time it might be. Linux was created with the user in mind, with all its versatility and flexibility, so the user feels comfortable with whatever (s)he establishes.

More Questions:
I am still not too sure how Linux makes so much money. How?
There are many other operating systems. Why was Linux so successful?
