That might make it incompatible with the GPL, but this is a typical
characteristic of many licenses -- including DFSG licenses.

Can you show me another DSFG-free licence that terminates depending on action taken not involving the covered work?

But the question is: how do these restrictions contaminate other software?

They limit the licensing of other works, maybe produced by the user, which may or may not be on the same media.

[Contaminate other software means that just being on the same media is
a problem.]

Problems with being on the same media is an *example* of contaminating other software, not the complete meaning of the term! That one even says "For example" in the DFSG explanations! It is not required that software on the same media is contaminated.

If there were any valid patent licenses covering this software, under
BSD you'd be in trouble for patent violation.

Yes, you would.

If there are any invalid patent licenses covering this software, these
clauses give you protection from litigation based on those licenses.

No, they do not, because they can be terminated by actions unrelated to the covered work.

If there are no patent licenses, this is indistinguishable from BSD's
treatment of those licenses.

I think I agree with that. The question is, are we accepting a non-free patent licence, or is the incorporated patent licence irrelevant?

If someone offered us a non-free patent licence for unspecified patents infringed by a BSD-3-clause-style-licensed piece of software, what would we do? I would like to obtain a list of patents involved and refuse the non-free patent licence.

My Opinion Only and possibly not of any group I know.
