If I had a photographic memory and I used it to replicate parts of GPLed software verbatim while erasing the license, I could not excuse it in court that I simply "learned from" the examples.
Some companies outright bar their employees from reading GPLed code because they see it as too high of a liability. But if a computer does it, then suddenly it is a-ok. Apparently according to the courts too.
If you're going to allow copyright laundering, at least allow it for both humans and computers. It's only fair.
