Maybe I'm stupid, but what's the point of internet-wide action for a national bill? I'm not represented in any US politician. I'm not entirely sure what I'm supposed to do here..
They mention the FCC as if non-US citizens are supposed to know what that is. They ask for a zip code, without asking for a country. The phone number they listed will not work anywhere but in the US. The address listed in their privacy policy does not name a country.
All this leads me to believe that the people behind this think the Internet only exists in the US, or that they are not even aware there are other countries besides the US. Don't worry, you're not the one that's stupid here.
