Prompted (provoked?) to do a more complete analysis (I was sort of avoiding naming).
So, doing
curl -i -L -H "Accept: application/rdf+xml" 
for all the 122 company URIs > get-out

[rover-2:~] hg% grep '<link rel="meta"' get-out
<link rel="meta" type="application/rdf+xml" title="RDF/XML data for Franz Inc." href="/goodrelations.rdf" />
    <link rel="meta" type="application/rdf+xml" title="RDF/XML data for Gnowsis" href="http://www.gnowsis.com/goodrelations.rdf" />
<link rel="meta" type="application/rdf+xml" title="FOAF" href="http://www.netestate.de/foaf.rdf">
<link rel="meta" type="application/rdf+xml" title="FOAF" href="www.reengineeringllc.com/foaf.rdf" />
<link rel="meta" href="./wp-content/plugins/wp-rdfa/foaf.php"type="application/rdf+xml" title="FOAF"/><rdf:RDF xmlns:rdf="http://www.w3.org/1999/02/22-rdf-syntax-ns#" xmlns:dc="http://purl.org/dc/elements/1.1/"><link rel="EditURI" type="application/rsd+xml" title="RSD" href="http://zepheira.com/xmlrpc.php?rsd" />
	<link rel="meta" href="http://www.tomtom.com/labels.rdf" type="application/rdf+xml" title="ICRA labels" />

Unfortunately this is almost the same as
grep "application/rdf+xml" get-out, which adds two more lines:
<!-- HTTP Request Header: Accept: application/rdf+xml -->
    <link rel="alternate" title="RDF/XML" type="application/rdf+xml" href="http://www.semsol.com/.rdf" />

So not completely devoid, but not a big percentage.
A couple of good relations in there.
A bit of Semantic Web, but doesn't really say much for Linked Data, I am sorry to say.

Note that I could not have done this as easily if someone had not provided the list :-)
If you want to see the file of all the curl outputs:
