Presumably they're worried about a disaster taking out your DC, which
is good, but they're not worried about any of a number of more likely
contingencies, which is bad.
The nice thing about tape is that the media are inexpensive. You can
afford to retain old backup data and logs for years or decades. How do
they plan to recover from a corrupted data base that isn't discovered
until the backup data are gone?

Tape drives may be more expensive, but the media are less expensive.

Yes, but it's not my dog.
