My analysis is at https://news.ycombinator.com/item?id=24874277 https://news.ycombinator.com/item?id=24874277 I agree that it clearly isn't an access control. I think there's a plausible case that it's effective as a copy control, as well as a plausible case that it's not. Re license: the control prevents further copies being made, which is clearly a right protected by copyright. Re your last point, the issue is likely (b)(1)(C), which is about marketing.
