The original story has been told for around 50 years with the widely noted implication "this was dickish behavior - they didn't have any particular preference for non-brown M&Ms but just wanted to mess with the people waiting on them". Even the 'debunkings' invariably recognize this interpretation of the original story.
Obviously part of the reason this story gets told a lot is because a lot of people, many of them management consultants who charge by the day for nuggets of catchy wisdom like this one, love the idea that organizations have a homogenous culture and the same ones that skimp on the buffet preparation also skimp on the rigging safety. Actually, this is complete fantasy. It's perfectly believable to think that the same boss makes sure the artists have everything in their dressing room they want, no matter how demanding, but thinks that they won't check the bigger, critical but more expensive stuff.
