That reminds me of one case, where an author of software saw any improvement or genuine feedback as a personal attack - directed at him and his "legacy". Can't go into specifics, but only features directly or indirectly praising the original software were allowed. I was student/intern at the time and learned about that the hard way. Still, one of most important teaching moment to this day.
