Full-page ad by NSA in the Communications of the ACM

I had a two-week saga trying to pay for my ACM membership this year. Paypal did not work, then my credit card was not accepted by ACM, and ACM support gave an irrelevant response as to why. The day after I finally managed to pay my membership, the February edition of the Communications of the ACM came out. It carried a full-page ad by NSA. In other words,

ACM is sponsored by NSA.

They help NSA spying on my mails, I knew that before. With this latest update on their relationship, I am beginning to wonder: why exactly am I a member? Let me look at the `benefits'. This is the list from their reminder to pay up:

• "Communications of the ACM magazine featuring news, analysis and insights from the computing world's leading authorities on the cutting edge of technology." And also full-page ads by NSA. I do not need this.
• "The option to subscribe to the ACM Digital Library, containing full-text articles from all ACM's magazines, journals and conference proceedings." I am an academic, my library has access to these resources anyway.
• "ACM Learning Center with resources for lifelong learning - online courses, online books, videos and webinars on today's hottest IT and business topics." This is something I checked out years ago when I became a member. It is so great I never used it since then.
• "ACM Tech Packs, annotated bibliographies compiled by subject experts." These are few and far between, and sooner or later there will be a survey paper published somewhere anyway.
• "ACM Career & Job Center" for jobs in the US. Universities from other countries seldom advertise. I have no intention of leaving Asia, this is irrelevant for me.
• "Mentoring opportunities through MentorNet". I am too old to be mentored and too young to mentor. Besides, I support a similar initiative which is not US-based: ResearchIntern.net.
• "ACM e-Newsletters that keep you current on the latest computing developments, and much more." The more interesting articles show up on Hacker News anyway.

They forgot to mention the forwarding ACM email address, something I rely on, unfortunately. Since this forwarding address is under the scrutinizing eyes of NSA, I am migrating to a new email address anyway. So why am I a member again?
