I find that limitation to "American" (surely meaning US american) people an incredibly embarrassing and nationalist call to action and it alone made me instantly close the tab.
Unfortunately, the Constitution of the United States of America, the sacred document that Mr. Levison was attempting to preserve, does not guarantee that right to every human being -- only Americans.
I look at it at a first step. Once we've "restored" the Constitution and managed to guarantee the right to privacy for those covered by it, only then can we start to "expand" that to include every human being.
I have many friends from all around the world and I believe 100% that all of us should be afforded that same right to privacy that the Constitution gives me, but we've got to start somewhere...
(Disclosure: I'm an American and I have and do donate to the EFF, EPIC, the Tor Project, and I happily gave to Mr. Levison's defense fund immediately after it was announced a few weeks ago.)
John Gruber at Daring Fireball has been doing a lot of work to encourage people to donate. I think the latest uptick has been the fireball effect at work.
