To clarify because there's a bunch of misinformation about this
the interview and questions was by "future game show", part of gamesradar
when they asked their community for questions for the diablo team on twitter, they received zero responses
they claim in their video description "Some of the usernames in the video have been altered for anonymity, at the request of the user". Some people keep claiming they added this after being "exposed", but they did not. I watched the video as it was uploaded, it was always there
However, it is likely that they forged most, if not all of the questions, as i said; they received no responses
What I do doubt is Blizzard's involvement with these questions as people immediately assume, but of course; people love jumping on the Blizzard hateboner bandwagon
