There is a difference between public repository run by volunteers and
professional enterprise sysadmin. Some time ago I developed LaTeX
package for a bank and it had to be verified by their sysadmin. The
employees can only use verified software. Thus they can use MiKTeX,
because it is verified by their sysadmin, but not TeX Live. Any
organization could block CTAN in the firewall, the sysadmin will make
a mirror of TL and if the sysadmin considers it stable, the local
mirror will be made available to employees.
