Wrong.
What do you think the 'L' in GPL stands for?
GPL code ≠ public data

I'm not going to engage in a flame war here. I clearly laid out references to relevant parts of the law: (1) What a license is and is not needed for under US copyright law (2) purpose of the GPL, and (3) distinction between copyright and data rights.
If you have any sort of citation for this nonsense, please post it. Otherwise, I'm checking out here.
When you say that a computer program "looks" at my data, because my code is for public, it means that the owner of the computer program use my code to make derivative work without obeying of my license, which is explicitly forbidden by copyright law.
For example, you cannot pretend that your smartphone is just looking at a copyrighted film in a cinema. Nobody will ever bother to ask your smartphone, what it's doing. Stop pretending that your smartphone can "look at data".
