Such as the FSF? A pure copyright license, such as what they claim the
GPL is, cannot protect against all of the things they want to protect
against, and so they make claims that aren't backed by copyright law as
to what makes a work subject to GPL.
For instance, suppose you have a GPL library, X, with a publicly
documented interface. No other library implements that interface. They
say that if you write code that can use X, your code must be under GPL.
However, suppose there is also a library, Y, that provides the same
interface as X, and Y is under, say, a BSD license. Now, according to
the FSF, you can write code that calls X without it being a derivative
work.
Copyright law simply doesn't work that way. The existence or
non-existence of Y is completely irrelevant to the question "is your
code a derivative work of X?". Y is relevant when it comes to trying to
prove the answer, but it does not change what the answer is (for
example, if you are accused of making a derivative work of X, and Y
exists, then you can simply claim you copied from Y, not X, and the
authors of X will probably have a hard time proving it was really X you
copied from).
