Let me post just one more thing to those that think any kind of language goes in the game.
The vox capability is an integrated part of the game, unlike teamspeak or roger wilco. That means that it is part of the game, and can be used in the ESRB rating.
Lets just take the rating for a mature level game: Titles in this category may contain mature sexual themes, more intense violence and/or strong language
If strong profanity was present constantly in the game, even if it can be 'squelched' it means the game could receive a mature rating. That means HTC could not let anyone under 17 play the game. You may say 'so what?', that is hard to figure out. Maybe, but it is a big hassle for HTC and the rating will hurt sales.
I have never understood why people think profanity for the sake of profanity is a funny or even cool thing. I am no prude, I can swear with the best of them but I choose not to. I find that people who continuously use foul language lack the intelligence needed to construct a cogent thought. I personally don't care if they do prove their lack of intelligence online but it does make me upset when children hear it. Kids do walk by rooms.
