The following comments are all directed to pre-"Reno" releases
since I have not seen the latter.

Most of the BSD 4.3 distribution is restricted and subject to
AT&T licensing. All of the earlier BSD releases were subject
to AT&T licensing.

A limited part (on the order of 10% based on file count) of 4.3
has been certified as free of AT&T licensing. This part only
requires acknowledgement of its source for redistribution.

The redistributable part is archived at uunet and, I presume,
other sites.

I hear nothing in life is certain but death and taxes -- and they're
working on death.
