Not sure about the Switzerland thing. My firewall sees connections from U.S. servers when installing and using it.
They may not have the HQ in the U.S., but if they still have servers in the U.S., we've seen with Megaupload, and now KAT, that the U.S. thinks its entitled to jurisdiction over the company.
So at the very least, the company should have its lawyers already work on a strong jurisdiction defense, if they want to be prepared and maintain their credibility once the U.S. gov comes after them.
All servers in the EU, the US connections you see are to proxies we use for better performance. Nothing stored there and chat contents E2EE, of course.
