Yeah we already discussed this. This is him taking a ridiculously laughable extrapolation from a simple statement. One that happened because it was the question HE asked and framed in a way to get an answer he could twist into how he wanted, supporting his awful headcanon he keeps trying to hamfist every new piece of lore into.
When there's no evidence for most of what he claims in this video.
His assertion, as somebody mentioned earlier in this thread, is that "Chronicle is purposefully misleading because the Titans are bad" when the only thing Blizzard's answer is actually says if you honestly look at it, is:
"We don't want to be held to what can only fit into Chronicle." It was Steven Danuser throwing out a lazy excuse in case they want to break their old lore to do something. And everybody who saw that answer and weren't looking to twist it into fitting an awful headcanon saw that.
