I let my membership expire years ago and haven't seen a reason to rejoin...ever.
If you are not a member of the ACM, you can read it in ACM Queue, in which it was published in January: http://queue.acm.org/detail.cfm?id=2090149 I somehow feel this is a very distorted view of what really happened. Perhaps it would be good if somebody "official" wrote a Letter to the Editor (Communications of the ACM publish them in every issue)? Wil.
