There is no difference to the victim if the company sends the ants directly, or if you receive the ants and then re-post it.
This is one of those ridiculous scenarios that security folks dream up. I imagine Schneier doesn't live in a concrete bunker with a blast door, because a regular door can conceivably be broken open with a sledgehammer. The vast majority of homes do not have a sledgehammer-proof door, because it's not actually a problem. Same with the shipping of ants.
There is no difference to the victim, but there is a difference to the company. In one case they are guilty of shipping live ants to an unsuspecting victim, and in the other case they're not even related to the incident.
