They aren't owned by Blizzard.

I'd imagine a licensee, hosting nearly all their games, has much more responsibility in their public statements compared to Blitzchung

I don't own the law firm I use to defend myself in court, but I do pay them to act on my behalf. Blizzard has also not done anything to backpedal on that statement. Honestly, how many mental hoops did you have to jump through to convince yourself that Blizzard doesn't endorse what NetEase said?
