While they would have maintained an archive, it is not necessarily
intact.  Even in a temperature and humidity controlled environment,
data will be lost.  There was a well known issue in the mid to late
1980s where tapes would fail due to the binding between the tape
and recording surface failing.  Maybe the equipment has failed or
replaced and space is required for other purposes.  It costs
thousands of dollars to transfer the old backups to new media (I
ought to know, I was hired to do this work on a relatively small
archive).  Then there is the matter of finding data: backups may
not be properly indexed so you may have to manually search for a
particular type of backup, then you have to find the specific item
you are looking for.

There are considerable problems with backing up data.  They exist
today, and they most certainly existed ten or fifteen years ago.
It is quite possible that Apple does not have functional or accessible
copies of a lot of their software.
