&quot; But for Google to say that unionization information violates their terms of service [1] may be defamatory&quot;<p>No, it isn&#x27;t.
Because that would require google having said that.
Google in fact, has said or written nothing as far as anyone can tell.<p>&quot;On top of that, Google&#x27;s action may violate the National Labor Relations Act.[2]&quot;<p>No, again, it almost certainly doesn&#x27;t.   This is a pretty ridiculous claim, backed up by roughly no case law.  It&#x27;s pretty easy to see it would swallow pretty much all law  if it was read the way you are :)<p>&quot;So Google could have a hard time in court over this, since a pattern of illegal anti-labor activity has already been established.&quot;<p>This would pretty much be inadmissible in court to show <i>anything</i>, as evidence of &quot;bad character&quot; is not permissible to show someone did something in a different case.
