Except that there IS personally identifying information available.
There is a delaware corporation formed. With someone who was as dogged as you are at NOT LETTING THIS GO, someone could look up who formed it and then internet stalk backwards.
And then, if the HC team posted some basics like "Jimmy has worked with 4 corporate mergers before" you could cross-compare on LinkedIn and other social media platforms fairly easily and, within a matter of a day or two, the weaponized autism of the internet would know the names, home addresses, phone numbers, and credit scores of the entire HC team and likely blow the whole HC/NCSoft deal apart.
So they are being VERY cagey for a reason.
For example, I mentioned in this thread that I've been involved in sales, marketing, and politics for a long time. Someone on here could figure out my location from some of my comments (not hard, I think I list my location in my bio even), hunt me down on Facebook (I have a 2 public pages on there) and out me as a video gamer (which no one would be shocked by). I'm careful not to say anything outlandish in text that can be screenshotted for that reason, even if it's "hidden" behind "anonymous" forum logins, because I assume that SOMEONE will eventually link them to me.
