The difference is, Enron was suspected of committing a crime. Lavabit committed no crime.
If the government subpoenas an individual for their encryption key, because they have reason to suspect the individual for a crime, it is different than to subpoena an innocent, indirect 3rd party. To me, it's like saying "We don't have enough police to handle this crime. So here - you have to take this gun and help us find the criminal. If you refuse, we throw you in jail."
Any service on the Internet could be used by all types of people, for good and bad purposes, just like a hammer can be used to drive nails or kill someone. You don't throw a hammer manufacturer in jail when someone uses a hammer to kill someone. Lavabit is an innocent 3rd party in all of this, regardless of how their computer system was designed.
