Just how did you determine what is the "correct" interpretation? Laws? They might be different between two countries, you can't even quote international treaties, because there's usually at least one country that didn't ratify any given one. Some authority supposedly versed in this? Link to the source.
My interpretation is that free is free, even if the links don't work. I don't care what corporations (especially now PGI or MS) say about that, and it's not just limited to this issue. If you say something, you'd better have a darn good reason to withdraw your statement (hint: whims and greed are not good reasons).
So, from my POV, it's not piracy, but saying "screw corporations and their whims". They gave permission, withdrawing it later like they did was underhanded and wrong.
