Yes, because they like Control Data products.
DtCyber is open source

they're called "controlfreaks" for a reason. From what I understand, COS is in fact generally
available because it's in the public domain.
The other OSs are not; they are distributed by permission of their owners. At the moment,
those permissions do not extend to making them available to the whole world. The keepers
of the archive of course honor the restrictions imposed by the owners.
In that respect, the situation is not significantly different from, say, that of VMS. VMS
is released under a hobbyist license, which is available by request. Controlfreaks is a
mechanism for making software available on a similar basis and is also available by
request.
