Q, Why do you assume the worst and imply something nefarious is involved? Duffy, like most accomplished people, tailors versions of his bio to create a cogent narrative -- and that often involves leaving out extraneous details that have little or nothing to do with the specific industry involved. Or simply because of space considerations. (Some websites provide a word count limit, etc.) Why don't you look at some of the other bios on the Xeriant website and compare them to other online bios about the same people? Especially the bios of people who have not focused largely on the aerospace industry. I'm sure there will be variations in length, content, focus, etc. And sometimes the person is pressed for time and simply forgets to include something.
