Didn't you ask the same thing yesterday? Apologies if it wasn't you. It's not about simply speaking out and having your 5 minutes of noble victimhood, no matter how truthful this is. You have to think about your reputation in an industry where future employers expect you to be tough, don't want to employ potential trouble makers or "thin skulls" and don't want to employ people with a history of whistleblowing.
Plus anyone putting their real name against a complaint or negative comment about Markle will get absolutely destroyed by her rabid Sussex Squad fans.
And finally, if you have suffered a real trauma - as the Hollywood Reporter seemed to be implying, with employees going for therapy - perhaps you just want to put the whole thing behind you.
