As a Contributing Editor and frequent contributor to The Star, generally the author is the one that has the right to reproduce said article first; at least that is in documents I've signed. The entire magazine is copyrighted, too.
The MBCA is not affiliated with MBUSA or Daimler and is not part of the corporate archive at Daimler
The MBCA is generally quite cooperative in letting articles be reproduced.
Peter, the Acting Publisher of The Star is Richard Simonds, so I suggest that you bring the issue up with him during the European event--I noticed he will be there with you.
I brought the article to attention here, for certain we like to ensure that everything is correct prior to inclusion anywhere such as our Tech Manual. One of the references listed as a "source" for such tags supplied some tags that are not correct for my car at least, and thus I am not certain that his knowledge is accurate on the topic. Best to get a consensus.
