I found it mildly interesting, that in written form, this reads just like an Ion interview. I haven't watched it, because honestly, I just can't be bothered, but the bullet points could just have easily come from Ion, as Morgan. Kind of surprised Ion didn't do this, too.
Which says to me, perhaps a lot of what Ion says in interviews are canned answers, and it's a "team" effort to get certain points across in these Q&As or whatever they call them in the moment, via a loose script. When you think how much they use(overuse) the phrase "the team", it wouldn't be shocking.
And yes, half of it reeks of dev ego defending their work. Which isn't surprising, considering it's Blizzard. But I just don't care enough anymore to get angry or anything over it.
