Don’t binary packages violate permissive licenses a whole lot?

The Go standard library, for example, is licensed under a three-clause BSD-style license that includes this condition:

Redistributions in binary form must reproduce the above
copyright notice, this list of conditions and the following disclaimer
in the documentation and/or other materials provided with the
distribution.

But which system’s binary packages of Go programs contain Go’s license, or those of the other dependencies included in the binary?

The answer is that The Go Authors don’t go after anyone else, and that clause simply isn’t enforced.
