No, I don't think they handle us differently (especially because I have friends who work/have worked with other sites who have similar experiences). Why would how big the site is matter? But more obviously: Why would they take the time to review all the questions in advance if they have the complete freedom to just say "I can't/won't answer that" in the interview?
These aren't live interviews for a reason. Companies who vet questions in advance are generally doing it for live broadcast so they aren't caught looking bad. Outside of Blizzcon -- where the stage moderators do vet -- Blizzard isn't giving live interviews with third parties. So they can just say "no" and you move on.
Basically this.
