I'm not as bothered by the lack of voice chat as much as I am people saying it's a good thing.
Indifference is one thing. Saying "yeah, it's great that this feature isn't in the game!" is another thing, and just ridiculous in my opinion. There are solutions to the problem of rude players: have the feature off by default, have parental controls to disable it, and enable people to mute. In fact, we can go a step farther and let people report abusive players, who can be reviewed by humans and have their voice chat privileges taken away. That one might be too much, since human resources are limited, but if they have the manpower, that's another way they can curb toxic behavior.
I can deal with no voice chat, but man, it just makes no sense to me to be glad a feature that might attract players is not in the game.
