With the risk of being flagged I may say that Blizzard did the right thing BUT ONLY if the interview was a an official post-match interview. Otherwise they did wrong, since they cannot force people into not telling whatever they want by any other mean.
I think it is the right thing to do in order to avoid future sociopolitical references in official post-match interviews: imagine someone saying 'power to the whites' or whatever in an live Blizzard interview. Like it or not, if you urge to call this move "censorship" you (and Blizzard) would have to tolerate slurs like that.
