No, the code is code. It is an artifact. The GPL is a legal 
document. The legal document says what rights you have to the 
copy you received and what requirements that follows it. You are 
allowed to modify it and do anything you want with it that is 
covered under fair use. This varies between jurisdictions.

The license primarily comes into effect  when you _distribute_ or 
_publish_, because the legal precedent for putting restrictions 
on distribution and publishing is much stronger. And WIPO is much 
more clear there.

So, if you build websites for a third party you can use GPL 
without redistribution by writing the contract in such a way that 
the third party is using your service. Meaning, you run the 
software. So circumventing the GPL isn't all that hard if you 
want to.

The AGPL also affects publishing as a service, so it makes such 
arrangements much more difficult.
