Many people think such accents sound more educated (or snotty, arrogant and and annoying, depending on the person).
Actually no almost none are. Just Murdo. Here's who isn't: Bob, David M, Dave P, David R, John Graham, Esteban, and most of the others...
Corrine or Korrine? sounded French or French Canadian Primal Kaur? Hard to tell but sounded Punjabi. Gile Marrache sounded French
French is not British, Australian, or South African. So Gilles is not part of your original point. He is head of Europe commercial. And Corrine is hardly leadership on the level of the entire list of people I mentioned. She's an svp and reports Murdo. Every single person I named was either the CEO or CEO staff. Corinne is not CEO staff. So you have not named one additional person in leadership.
