I can easily say that every academic I know and have as friends, which is all but two people, have surely “flagrantly violated copyright law”. I have no doubt. They have even asked me for help doing it. I can also tell you that none of those have ever read one of those copyright transfers. I did, once, but I do not understand law-speak and do not remember what it said. I just know that my university had that as a policy – because of lawyers – what we had to do to redistribute our articles. That is also why I had a “may not” in my comment and could only refer to anecdotes, because, surprise, I do not understand the exact details about this. But you know this, because that was in my comment.
