I'm sorry but you seem to be missing the point. That under the license
using GPL code in your program means you are required to GPL
your whole program, therefore if one agrees to use GPL code in
their original work, then said original work must also become GPL
(due to the terms), thereby increasing the amount of GPL code by
one and decreasing the amount of non-GPL code by one.

Let's say I write a 50,000 line program, with no GPL code in it.
It's not GPL unless I want it to be. OK, now I decide to use 5 lines
of GPL code in it. Now I have to make the whole program GPL.
So I (reluctantly) do. The amount of GPLed code in the world
has now been incremented by one, and the amount of non-GPLed
code has now been decremented by one.

But if I use 3 lines of GPLed code in a 300,000 line ORIGINAL program
that really an "extension" of the GPLed code? I don't think so -- the
ORIGINAL program would likely be RADICALLY different from the
GPL program.

So then "public domain" is not fair, according to this claim, because
one can use public domain code in their works and do whatever they
want with the combined work (that's why it's called "public domain"
because it is un-controlled by copyright law)? According to you
"public domain" should be shunned. Am I right? If so, I want to say
I do not subscribe to that school of thought.
