No, you are wrong.
If your code link to another code and call functions and share data
structures with that other code, your code becomes a derived work of the
It is however true that you don't have to worry about that if the other
code is licensed to you under an open source license and as long as you
don't distribute your code.
But i f you distribute your code, even if it is without the other code,
you must take the fact that your code is derived from the other code
into consideration. If the other code is under BSD, MIT or similar
license, it's easy: apply whichever license you like (almost). But if
the other code is under GPL, you must use GPL yourself.

How can GPL infringe on the freedoms of free software? GPL was after all
developed by RMS and other to protect the freedom.

I agree that compiling a list of contributors, similar to the Linux
kernel, would be a very good thing to do (if feasible).

I have not propound any sort of dictum. I have only tried to shed light
on something which great many people seems to be difficult.
