Well. With all due respect to the FSF, this is an opinion how they would like
to have the license interpreted. However, if you study i.e contract law, you
will learn that only because a something is in a contract, it does not mean it
will be enforced exactly the same way by a court. In fact, one could say that
you will hardly find a contract the is 100% valid in the way it is written.
Just look into the terms and conditions that you get from you bank or your
credit company and ask a lawyer if there are any unenforceable clauses in
Similarly, it was Apple's opinion, that they have the right to disallow you to
"jailbreak" their devices. However, as we have just seen, the Library of
Congress has a different opinion about that, and has given it as an exception,
an example that does not fall under the copyright law.
As long as we do not have courts finding that the distinction between same and
different user space is acceptable, we do not know if this interpretation will
be accepted by courts. There is certainly reason to argue that if you do not
copy anything, you cannot infringe copyright law. I can, i.e. buy a book, and
change the contents of the book by adding hand written commentaries. Under the
first sales doctrine, I am also allowed to sell this book at a later stage. No
copying has taken place, there is no issue under copyright.
If you have a case where a court has decided on this issue, please give me the
reference, that I can study it, however, I have not seen any example that
would cover this issue.

Again, Interpretation. We need test cases to know how to see this in the
context of the entirety of law.

It is not unrelated to the discussion. If you follow the discussion about the
Pystar case, there was a lot of discussion on groklaw how the outcome of the
case would influence issues with GPL. It is also clear that the First Sale
Doctrine was confirmed by the court, but it found that it did not apply to this
particular circumstances IIRC.
The fact, that Apple has a proprietary license and GPL is also irrelevant in
regard to copyright law. Both a subservient to copyright law and hence can
only operate in its space. You cannot as an example extend your copyright to
1000 years in form of an agreement or a license. Similarly, any other
conditions you put in a license are not automatically legally binding because
you include them unilaterally,. While there is a legal principle called
freedom of contract, this principle is severely limited by statutory and
common law. Just look about case law about warnings of limitations of
liability towards patrons or trespassers. Most of those are rather instruments
of imitation than valid legal agreements.

if you don't distribute this is not an issue. The problem Pystar had was that
they distributed their code together with Apple's software which was legally
bought. However, I do not think that court tipped their hands in any way hwo
they would have found if Pystar would have only sold their software and had
the user obtain a legally obtained copy of Apple's software.
Similarly, I suggest that it makes a difference if the theme contains any
copied code or not, and if it is distributed with word press or not. There is
nothing, I can see in the GPL license that forbids me as a user to use a GPLed
software with any other software irrelevant of its license.
I did not referred to the Pystar case, because it is exactly the same
circumstances, however, I referred to it, because it is the closest case that
I have watched that deals with this issue in a broader scope.

Who violates the GPL if a theme without any code in it that is copied and
pasted and is not distributed in conjunction with anything else, but it is use
together only by the user?

I was not talking about redistribution. I was talking about distribution about
independent elements that are used by the user in conjunction. In a side note,
it is not commonly accepted by the legal community that a license is also a
contract. I have seen arguments that have tried to make such a point. However,
it is not clear that all the necessary elements for the formation of a
contract can really be established. Therefore, it is not clear if any terms
that reach out of the direct purpose of the particular license will ever be
The commercialization is a total different story. As long as the GPL exists,
GPLed software has been successfully sold. Just look at linux distributions
that sell CDs with GPL software on it. They do not do it only once. There can
be many reasons why someone rather buys than downloads GPLed software.
However, this is really not the point here.
The question that I find intriguing is if we believe or really want that a
license can be binding outside its scope of purpose, or if we maybe think that
the 4 freedoms expressed by Richard Stallman are universal rights in the sense
of human rights. In the latter case, the license would be irrelevant anyway,
since such rights than would be universal and applicable in any case. In the
firsr case the question would be if copyright law is or should be applicable
even if no copying is performed.
