*Support, in principle.  The existing name is misdescriptive.  It would be appropriate if the article covered only portion in the "Massacre" section.  I agree that "Munich massacre" is the common name for the events in that section (and I have no doubt that it therefore gets a lot of google hits, or that it gets the most google hits, since that's the most critical part of the article); but it is not the common name for the entire subject of the article, which includes the hostage-taking, the massacre, and Israeli response, among others things.  The massacre makes up only 10% to 40% of the article, depending on what you count.  My only quibble (and hence my "in principle" qualifier) is that I suspect the common name for this is actually something more like the "Munich Olympics hostage crisis", rather than "1972 Munich hostage crisis".  I suspect that more people associate it with the Olympics than with the year 1972.  But either is an improvement over the current misdescriptive title.
