For companies like Twitter, being based in the US seems to have become something of a liability. There's Google, Apple, et al attempting to quell international concerns with promises of better encryption... I wouldn't be surprised if one of them just up and moves their operation overseas. After all, some of the up-and-coming open-source competition is a decentralized, globally distributed organization and not under the thumb of any nation state per se. They have the luxury, I think, of cherry picking the best privacy and security policies, and can open the kimono on their source code to prove it.
