Ya'll need to relax. You're taking this video entirely too literally. It's meant to have the look and feel of kids' nature programming, where the actors are unnecessarily animated and overly cheery even while animals rip each other to shreds in the background, so as not to terrify the kids.
Blizzard is not literally saying you are little boys and girls.
This has been Blizzard's style and sense of humor from the beginning. It's cheeky and silly. This isn't one of their better efforts, but ya'll are at peak overreaction.
And if you think they are jacking up card prices to pay for ... well, this, then you have no idea how little this cost to throw together compared to the cost of the electricity Blizzard's servers consume every 5 minutes.
