Why wait 1.5 months to make an open letter after a "June 13th, 2012 at 4:30pm" meeting? Did you try communicating directly with Facebook for 45 days, then let it go? What makes now the best time to incite public wrath against Facebook (I'm assuming that was the intent in resolving never to write another line of code for a "rotten to the core" company) in an open letter that was anything but conciliatory?
It sounds like Facebook used some hard-handed tactics, but I'm more curious as to your choice of timing.
Edit: not trying to be snarky, genuinely curious.
