What looks like anyone can read the various cron files?

If it happens, your installation/distro is broken and seriously needs to
be fixed. If *YOU* don;t understand permissions, please investigate
them.

As far as I know... crontabs for individuals are not readable by even
them without using crontab.

$ cat /var/spool/cron/greg
cat: /var/spool/cron/greg: Permission denied
$ crontab -e      #(allows me to edit my crontab and it is valid)
$ ls -l /var/spool/cron/greg
ls: /var/spool/cron/greg: Permission denied
$

Now if you are talking for the files in /etc/cron.(d|daily|weekly|etc),
then that is not a problem and these are typically used for
non-passworded systems daemon maintenance like Log rotation or updating
the apropos DB (aka whatis)

Please investigate permissions before you make more problems for
yourself. (the 10 characters at the beginning of the long listing)
