Why do you think a company anywhere would have more luck than Lavabit when presented with a legal search order?
I would also note that it seems incredibly clear that Ladar Levison knew what was at stake: for himself, for Snowden, for his company, and for his users. His decision to shutter his doors was his last option to protect their 4th amendment rights and I'm absolutely amazed he made the right call here.
Kudos to a brave man.
