In my opinion you are wrong.
I strongly dislike the notion that there are mannerisms, ect.. that are uniquely Japanese or more broadly Asian because that's just another form of Orientalist reductionism. Saying that kawaii culture is "uniquely Japanese" is wrong because while there maybe things that may be uniquely Japanese this is certainly not one of them, it's an amalgam of otaku and weeb dreams, Japanese and Western, but simultaneously neither. It's manufactured bullshit packaged and sold.
To address your other points, as I mentioned, nothing in that thread was explicitly creepy, per say, although I'd argue intent makes a large part of that. What I found pretty creepy is that weird double take during the Bethesda conference where suddenly, the thread went from talking about the games to talking about her, which I mean is
pretty weird but also at the same time perfectly expected. That thread is a continuation of that, where a woman's personality, mannerisms, and fan art drawn about her is apparently more important than the game she's making or the credentials she has to make said game.
All this is to say that she can be cute and adorable because that is her right. But, no offense, if you expect me to believe that there aren't thirsty AF weebs in that new thread thinking about their new waifu queen then, well, I've got a bridge to sell you dude. Yeah, I can't point explicitly to one person because it's not a black and white situation. But it's definitely there.
