When it first started happening, I heard the excuse it
was a case of
 industrial espionage gone wrong where an ingredient was left out of
 the recipe.  Now it sounds like it's done as a cost savings. 
Industrial espionage _is_ cost savings: it's cheaper to swipe something
 from a competitor than to develop it yourself - or, at
least, when it 
isn't then industrial espionage is a stupid thing to do. :)
