I know any legitimate hosting company would never do this, but it would be amazing if they just "happened" to have very loose security on the servers that hold Megaupload's data, and if some hacker were to..."gain unauthorized access" and wipe all the data.
They wouldn't be held responsible for a breakin, would they?
If a court orders them to take "reasonable, and industry best practice computer security approaches to prevent the data being lost", then, yes, they would be responsible for "accidentally-on-purpose" leaving the servers accessible. If it were to happen, someone would do a post-mortem, find out that they intended for it to be broken into, and then they would be guilty of contempt of court/destroying evidence/etc.
