OK, my other problem with Free Software is when Free Software proponents try to tell me that GPL is more free than BSD because GPL stops the software from becoming part of non-free software.
It's like saying people in the US are more free than those in the EU, because the US restricts travel to non-free Cuba.
It's not really. The concept of a derived work does not apply well to countries, but if it did that wouldn't be an example of it. What you're describing sounds more like a Free software web browser that would only communicate with Free web servers, which of course isn't what the GPL says at all.
