This is a really good point and something that the anti-SOPA movement should address better (or at least publicize better). I imagine phoning into the American consulate or embassy tomorrow couldn't hurt! They will say "we don't control that" but you can just let them know you are upset about WP being out, upset about SOPA, and liable to stop using US 'net services if becomes clear that the US market is "unsafe" for 'net business. I'll edit if I find more specific information for how non-US people can oppose SOPA.
