It does very little good to just "incorporate offshore" and still have US operations, US principals, etc.
If you're a US citizen doing something questionable in the US, you have basically three choices: try to do it in a compliant way, renounce your citizenship, or leave the US and/or operate underground and hope you never get caught.
While I have problems with the US Government's actions in the terrorism/cyberspace regulation/IP spheres (particularly in that the legislative branch has totally abdicated its role in oversight, as well as being generally incapable and obstructionist in general), I'm a loyal US citizen, respect the laws of the US and its political process, etc. So, all I'm willing to do is try to do things in a superior technical way, or to try to get the laws changed in the US.
The silent circle guys are basically all US citizens, and as far as I'm aware, equally wedded to the idea of US legal compliance.
