Reversability is the main difference - the disgruntled fired ex-sysadmin
can encrypt everything and promise to restore it for big bucks plus amnesty.
On the other hand, hiding the backup tapes and shredding everything is
relatively reversable as well, and has the advantage that you can
threaten to sell it to the competitors, so it's not much different.
When I was an undergrad, an ex-sysadmin left the University,
and a week or so after he was gone, the database system announced
that it would self-destruct in a week. They had to keep the system
shut down for a couple of weeks and change the system clock while
they hunted for the time-bomb, and the same sort of thing could be
done in many modern systems without crypto, though crypto makes it easier.
