Linux itself consist of the Linux kernel + GNU tools + other software from many
persons. So 'written by more that one individual' and open source. Just FYI,
windows browser, IE uses code from IJG (Independent Jpeg Group) to handle Jpeg
images. So are you now going to brand IE a clone? I suppose you will stop using
it now, will you?

In any case, M$ is making money out of it. We are talking about free software...

I don't see your point. Looking at the source code of a program, you learn
ideas, and a sometimes new algorithms. And then you can write the whole engine
yourself. This is also ok. You can take the older engine and modified it to
create a newer engine (If the laws allow that), and this is also ok.

What is the difference between learning the through papers and learing through
source code? Only this: Learning how somebody else has done this allows you to
avoid making mistakes that he might have made.
